Acceptable Targets: For the site's commenters: racists, Conspiracy Theorists and sometimes religious people as a whole. For the people mocked: atheists, gays, interracial couples, left-wingers, non-whites, Jews, women, and heterosexual White Anglo-Saxon Protestant males who dare not hate all of the former.note The saddest part is that most of these people actually mean it. Unlike Encyclopedia Dramatica, almost none of them are simply joking.
Quite notably, Andrew Schlafly's declaration that "E=mc2 is liberal claptrap." Notably, this stems from his dislike of moral relativism, which has absolutely nothing to do with general relativity.
Every quote in response to the net neutrality decision is guaranteed to feature the quoted fundie completely misunderstanding what net neutrality actually meansnote to quote Wikipedia, it's "the principle that Internet service providers and governments should treat all data on the Internet equally" - every fundie talking about it instead thinks it's something like the government taking complete control of the Internet. The commenter Nemo put it best when stating that "I have yet to meet a single opponent of net neutrality who can explain to me what it even is".
Fridge Brilliance: Yes, even the fundies get their moments. Vox Day, from the site Vox Populi. His name may look like gibberish... However, if one pays close attention, one could realize that his name sounds like vox dei, which means "God's voice" in Latin, meaning he thinks his word is God's word.
More likely, a simple reference to the phrase "Vox populi, vox Dei.", which means "The voice of the people is the voice of God." I.e. "this is what the majority has decided, and that's that". Not quite the same connotation.
Actually, follow the transitions from Vox Day to vox dei to vox theo to voice of theo, and then look at Vox Day's real name, Theodore Beale...
Fridge Horror: This. At first it just seems run-of-the-mill creepy, then you start to do the math and a slow realisation sets in...
"Funny Aneurysm" Moment: After a fundie made a ludicrously inaccurate statement about how the media wouldn't say anything bad about Obama even if he were caught red-handed doing something incredibly illegal, one commenter took it upon himself to "fix" the quote so that it better represented reality, claiming (paraphrased) that Rush Limbaugh wouldn't lose his popularity with Tea Party types even if it became known that he was friendly with the likes of David Duke, Hosni Mubarak, and Joseph Kony. Fast-forward less than a week, and Limbaugh declares his public support for Kony's terrorist organization, and, surprise surprise, the only people who criticize him for this were those who already opposed his worldview. The aforementioned commenter even hangs a lampshade on this trope.
Internet Backdraft: Extremely antitheist quotes will inevitably spark a debate between antitheists and those who deny that atheists can be fundamentalists, and the rest of the site. Usually with some variation of arguments on religion being the root of all evil.
Vocal Minority: While there is a definite liberal bias, the main reason conservative Christians appear to be targeted by FSTDT is because they tend to be a lot louder than other types of fundies. As stated on the main page, non-conservative and non-Christian fundies are fair game, but it would be a lie to say that there is no bias whatsoever.
Wangst: Oh so much. About half the quotes are guaranteed to have at least one comment summing it up as something like, "WAAAAH! Why won't you tolerate my intolerance?"
