Are atheists ever called "bigots"? I mean don't you have to be AGAINST something in order to be considered?

a bigot? What are they against? (other than God-people/religion?) I am serious. I couldn't think of anything they are against that would be considered bigoted. Is that because they are FOR anything and everything??Well, pretty much. Not saying that is a bad thing; it just popped into my head because people of faith are so often called bigots, you know what I mean Vern?
