I guess I'm a bit late to this one (since it's almost 90 comments strong now), but how do you respond with a straight face to a post entitled "Your Women Are Ugly!" is not a political argument" with comments that can roughly be summed up with "yeah, especially when they're ugly!"?
I know I'm a broken record on this, but it just keeps coming up. A person's perceived attractiveness isn't a valid basis for political criticism. It doesn't matter how attractive you think Ann Coulter is. Whether she's hot or not doesn't change the message she's spewing, and it doesn't validate or invalidate the hatred in her message. When you attack her appearence you're not criticizing her message, you're actually, in some way validating part of it.
Yes, Coulter repeatedly tries to sell or is sold as this attractive conservative voice. She does try to invalidate liberal opinions by suggesting that they're unattractive, as though a person's beauty is a valid basis for criticizing arguments. When you say "but you're not hot, Coulter!" you're not countering her argument. In fact, what you're really doing is validating it in some way. The implication is that her argument is wrong, not because looks don't matter, but because she's not hot. In other words, her premise is fine, just her conclusion is wrong.
So, I'm just going to go ahead and keep on saying it:
If your response to that post was to point out how you think that conservatives are ugly or that liberals are attractive, you didn't help. You reinforced the problem. What you're saying is "they're wrong because we're hot or they're ugly" when you ought to have been saying "they're wrong, it doesn't matter how attractive you are, but, rather, what your socio-political acheivements are." When you focus on people's looks instead of their contributions, you're just reinforcing the notion that the most important thing a person can be is pretty.
