The idea behind this discussion is to talk about and list all the logical fallacies people commit.
I've never been a big believer in "Atheists = Logical". Even less so now that I've seen some people arguing on here.
I'm also guessing a lot of people never actually took or studied debate, since I've seen so many cases of "You used an ad hominem! I win the thread!" on here.
Especially since, upon looking at the abuse of the "ad hominem" claim, it usually was an insult born of frustration with someone that wasn't addressing the arguments of their opponents.
Ad hominem, for those of you unfamiliar with it, is attacking the person instead of attacking their argument. If they address your argument, the claim of ad hominem isn't enough to dismiss the rest of their rebuttal.
In other words "Bob used an ad hominem in his arguments. Therefore Bob is wrong." is fallacious.
So what are some of your favorite used, misused, and flat out abused logical fallacies?
