Sadly, sometimes an atheist is someone with one less stupid idea than a theist. Atheism is no guarantee of intelligence, common sense, or any sort of virtue.
There are some people it's just not worth arguing with. I'm certainly more interested in condemning this asshole than working through the the logic of the ethical issues. There are no very complicated ethical issues: it's uncivilized, undignified, obnoxious and rude to leer at women. End of story. And I have better things to do than try to chip through this asshole's self-righteous misogynist blather, a task as full of the-stupid-it-burns futility as discussing the ontological argument with Metacrock. Especially since PZ has said all that needs to be said on the subject. All you can do is shake your head, mutter, "Wow, what a creep," and move on to something sensible.
Any time someone complains that everyone who disagrees with him is being dogmatic and close-minded, you can be pretty sure you have a crackpot on your hands.
