Basic Trope: Someone who sees sexuality in black and white terms, based on heterosexuality with rigid gender roles for how the man and the woman should be.
- Straight: Bob frowns upon homosexuality and other "deviant" activities.
- Exaggerated:
- The above-mentioned "deviant" activities include sex in positions that don't look like the woman submitting to the man, sex before marriage, and sex that's enjoyed for its own sake without an end-goal of reproduction. He not only protests a bill that would allow same-sex marriage, but argues that accepting same-sex relationships makes all opposite-sex relationships worthless.
- This extends even to matters beyond sexuality, such as not allowing women to work outside the home.
- Bob wants to get rid of homosexuals.
- Bob doesn't even allow same-sex friends or siblings to express their relationships passionately enough to make their sexuality look too ambiguous, and forces them to act cold toward each other.
- Downplayed:
- Bob belongs to a religion that believes homosexuality and other "deviant" sexual practices are sinful, but the most we see of it is Bob casually showing discomfort at the sight of same-sex public displays of affection.
- Bob hates all forms of sexuality, but will tolerate heterosexuality because it "serves a purpose".
- Bob has no problem with homosexuals themselves and basic relations thereof, but doesn't approve of same-sex marriage for religious reasons.
- Bob has absolutely no problem with homosexuality; transgender issues, on the other hand...
- Bob openly despises Pride Parades, flamboyance, diversity quotas, LGBT education in schools, transgenderism, and the more outspoken activists, but doesn't mind Charlie and David being gay and acting "normal".
- Bob has no problem with lesbianism because Girl on Girl Is Hot; however, male homosexuality, on the other hand... (Or vice versa if Bob is a He-Man Woman Hater.)
- Bob has no problem with Ms. Fanservice Lipstick Lesbian because Girl on Girl Is Hot; however, he still despises Butch Lesbian and Gonky Femme Lipstick Lesbian for not "pretty" enough to turn him on.
- Bob only brings up his anti-gay views when it's appropriate to the conversation, and can interact with non-Depraved Homosexual normally.
- Justified:
- Bob has deep-seated issues, such as past sexual abuse, that cause him to think this way.
- His past experiences with sexual minorities cause him to stereotype them very negatively.
- Bob was raised in a homophobic environment and/or comes from a time of Values Dissonance
- Bob was raised by a religious order which believes that heterosexuality is the only acceptable sexuality.
- Bob is a member of a religion that states heterosexuality is the only acceptable sexuality but permits peaceful co-existence with people of alternate sexualities.
- Bob is in charge of a group that's agreed to have as many children as possible (such as Space Colonies).
- Inverted:
- Bob believes that heterosexuality, reproductive sex between a married couple, and traditional gender roles are deviant and wrong.
- Straw Feminist: May hate heterosexuals (instead of homosexuals). May still hate sadomasochists, however.
- Ethical Slut: Being the opposite kind of character in the same kind of setting.
- Depraved Homosexual / Bondage Is Bad: The "deviants" are the bad ones. People trying to stop them are merely morally upstanding concerned citizens, not necessarily heteronormative crusaders. And if they are, they are of the Noble Bigot or Strawman Has a Point kind.
- Bob believes that failing to fight against/defy The Man and his 'constrictive sexual morality' — meaning doing anything that resembles heterosexual, reproductive sex — means you are on the side of The Man. He does not believe in taking a third option, and might even be rather against bisexuality.
- Bob accuses anyone who is heterosexual, homosexual, asexual, a virgin, prefers monogamous relationships, or just isn't that into kinky sex of being a Sour Prude and may even be prejudice against them.
- Real Women Don't Wear Dresses: Further than hating traditional gender roles, they may hate heterosexuality as well.
- Subverted:
- Bob rails on Charlie and Donald for acting like a bunch of "mincing queers" — they later find out it was a Stop Being Stereotypical speech, and Bob is a Straight Gay.
- Or Bob believes that this activity is wrong, but he also believes in letting people act as they want without harassing them.
- Or Bob turns out to be The Fettered in his beliefs and labeled as a Crusader only because of the opposite side's attitudes towards those of his beliefs due to a case of He Who Fights Monsters.
- Double Subverted:
- ...who stubbornly insists that having sex with men doesn't make him gay.
- ...Or so he tells himself. In actuality, he's a menacing bigot.
- Parodied:
- Bob acts less like a Moral Guardian and more like a "Stop Having Fun" Guy...
Bob: No weird positions! No kinks! No items! Fox only! Final Destination!- Bob Time Travel into the Have a Gay Old Time era, and Bob goes bonkers whenever he hears the word "gay".
- Zig Zagged: Bob believes that homosexual activity is wrong, but sees harassing gays for simply having the temptations wrong as well.
- Bob has older views foreign to both the modern tolerant and the homophobic perspectives- he considers same-sex romantic friendships important and views fear of same-sex intimacy deeply unmanly but considers gay sex abominable.
- Averted: Bob never discusses his views on sexuality.
- Enforced: It's an Author Tract about sexuality.
- Lampshaded: "Bob has some... issues about gay men. Makes you wonder, doesn't it?"
- Invoked:
- Bob learns in religion class that anything other than a married male-female couple having sex for reproductive purposes is wrong and that he need to fight to "protect" marriage, etc.
- Alternatively, Alice give a little speech about the destructiveness of heteronormativity and discrimination, maybe accusing Bob of being a bigot while she's at it.
- Exploited: Charlie and David deliberately kiss each other in front of Bob in order to provoke the latter to punch them in front of the crowd.
- Defied: Bob makes an active effort to be open-minded about sexuality, gender roles, etc.
- Discussed: "Bob, what's with hating the gays?" "It's a disease, Alice. Those filthy sodomites are diseased, and I'm trying to persuade them to seek a cure for their illness."
- Conversed: "OK, so this character hates gays. And bisexuals. And bondage. And masturbation." "Is there any sexual contact he likes?" "Well, maybe the kind within religiously-recognized heterosexual marriage for the purpose of reproduction, but only if it's in the missionary position."
- Deconstructed:
- Bob may be feeling insecure about his own sexuality, and puts others down (or hurts them) to make himself feel better. This may stem from any number of things, including (but not limited to) his culture and his religion.
- Alternatively, Bob has religious beliefs that make him believe homosexuality to be bad but also influence him to "hate the sin but love the sinner". He believes that there is a "gay agenda" that hurts people by corrupting them into gayness, but that it's best not to target the individuals, just the behavior, but to do it as ethically as possible. Unless he lives in a setting where there actually is an evil gay conspiracy, he's a Troubled Sympathetic Bigot.
- And, of course, there's always the fact that such kind of people can instigate others to perform terrible deeds for the sake of their crusade, eventually leading to a lose-lose situation for everyone, as the LGBT community ends up as the target of all their atrocities, while the non-radical, genuinely nice religious people end up taking all the flak for their horrible deeds.
- Reconstructed: At the end of the day, whether Bob accepts homosexuality or not, he just doesn't want to take part in it himself.
- Played For Laughs:
- Bob is getting into Lawful Stupid territory.
- A scrawny, weak, pitiful Camp Straight Bob makes the "stop being deviant" threat to Hunk Manly Gay Charlie and David. They promptly put him in his place.
- Played For Drama:
- Bob kills someone who he feels is "deviant. Or rapes her: A so-called "curative rape" based on the theory that it will make her stop being a lesbian or masochist or whatever.
- Bob at first is portrayed as the Butt-Monkey, however because of his charisma and wit he was able to convince a large number of people to march straight to Stonewall and ''cure" it.
- Played For Horror: Bob is a Serial Killer who targets particularly queer people.
