In the past, the situation of mutants in the X-Men comics was compared to racial minorities. More recent books have shown a tendency to make discussions of being a mutant sound like they're about homosexuality.
The classic (if Anvilicious) EC Comics story "Judgment Day", in which an examiner comes from Earth to see if a planet inhabited by sentient robots is ready to join The Federation. It's revealed that the robots are split into two groups identical except for the color of their outside casing, and the educational programming given to each color. One group of robots is given less useful programming, forced to live in inferior housing in a segregated part of the cities, relegated to less desirable jobs, etc., all based on the casing color. The examiner is forced to flunk the civilization, and the guide whines that he is "only one robot" who can't change the system. The examiner consoles the guide by mentioning that Earth used to be like this too until its people got their act together. Then the examiner gets into his spaceship, takes off his helmet, and is revealed to be black. Read it here!
In an arc of Iron Man, the armor is struck by lightning; this, in combination with Y2K, made it sentient. Tony wants to transfer its mind to something less dangerous, or kill it, but then the armor tells him that it loves him. "How would you define the feelings I have for you? Because, if what I learned from your mind is true — it feels exactly the same as what you feel — for Ms. Fujikawa." Tony then decides to see if he can be a better Iron Man while in the sentient armor, but can't control it... The armor claims to be protecting Tony, and then it stops letting his friends over. He puts on an older Iron Man suit to try and escape, whichenrages the armor, and it takes him to an island and tortures him, then apologizes.... Evidently, Steve Rogers taught Tony how to escape from being tied to a tree, and the thought of him gives Tony strength. Still, Tony has a heart attack during the fight, and the armor, horrified, does a Heroic Sacrifice/Redemption Equals Death. Among many comic!Iron Man fans, the sentient armor is generally called "Tony's abusive boyfriend".
My god. It's like somebody loaded Lifetime and the Sci-Fi Channel into opposite ends of a particle accelerator.
One of the now-obliterated comments on the original post for this arc went like: "So if Peter × Symbiote = OTP, and Tony × Armor = OTP... Peter×Symbiote×Tony×Armor is?"
Wait wait wait... according to the armor, Tony wants Ms. Fujikawa inside of him?
Apparently whenever She-Hulk has a transformation from her puny human state into the green goddess, it is the equivalent of sexual orgasm to her, as was showcased in not only the recent Ultimate incarnation, but on the classic 90's cartoon as well, which was supposedly for the "younger" crowd.
After Superman gets temporarily de-powered in the events of Infinite Crisis, Lois' assurances that she loves him, that it's perfectly understandable, that she's sure he'll be back to normal in no time, and even that she loves him for who he is and not how well he can perform, sound rather like Superman is having a different kind of performance issue.
In a Dilbert comic, Tina got in trouble for sending a dirty e-mail and Catbert decided to look the other way if she rubbed his belly. It has a hell of a subtext:
Tina: This seems so wrong. Catbert: Try using both hands.
A Far Side panel had the Big Bad Wolf on a psychiatrist's couch, confessing that "on and off I've been dressing as a grandma ever since."
This becomes even more blatant, or perhaps just more up-to-date, in Bizarro's take on it.
