I point out his race, because African Americans sort of make white a minority in my area. A majority of African Americans are very religious, or at least make church a big part of their life. I know from an African American Atheist who happens to be either engaged or married to a white women, that it isn't well accepted within his race (African America) the idea of atheism.
In fact, it is easier for a white person to be atheist than a black one. If anyone is offending by my use of either "black" or "African American" oh well, I've tired of trying to please everyone when using one term makes one person happy and the other very mad.
I think that's true. It certainly does seem that most atheists are white (and male). I think there's even a Myspace group now for black atheists and agnostics because they are so rare.
Anyway, back on topic:
I've never really experienced much discrimination, aside from middle-school stupidity in response to my middle-school stupidity.
However, just the fact that I have reason to be afraid to tell people I'm an atheist indicates that society is, at least, not very accepting of atheists.
