If you mean that atheist discussion tends to show racism, i.e. a belief in the inherent superiority or inferiority of groups of people with certain similar genetic characteristics, then I would say "Not in what I've read; they tend to focus on cultural differences and ignore superficial biological differences."

Two kinds of racism honey.

Old: about biological prejudice

New: about cultural prejudice. So showing cultural prejudice is a kind of racism.

'new' racism tends to be what's causing a lot of the problems in australia at the moment, or at least is what people will admit to.

(Shorthand version of a lecture I sat through for TWO hours, and almost managed to stay awake for so people, correct me if I'm wrong here, I have to give a talk on this next Tuesday).

And of course you've got the brilliant thing that if any culture is steeped deeply in a religion, evangelical atheists are going to have a problem with it, therefore showing 'racist' tendencies. The sensible ones, probably less so, but discussions tend not to happen as often with them.

Guess what, arguing this with you counts as homework :D
