You should actually read the
article. But anyway, I'm not sure I should laugh at the notion of less educated americans or at the "we didn't ask latinos and blacks because those morons go to church because yo momma said so" attitude.
It's a matter of culture. In Europe, atheism, or at least agnothicism, is very related to education, but in southern countries like, unfortunately, my own, and Spain, there's still a lot of fairy tale believers because yo momma said so.
Keep in mind that 'yo' should be read as 'their', it just wouldn't sound so silly.
