Non-believer Discrimination
From here:
Every single study that has ever looked at the issue has revealed massive amounts of bigotry and prejudice against atheists in America. The most recent data shows that atheists are more distrusted and despised than any other minority and that an atheist is the least likely person that Americans would vote for in a presidential election.
…
The most recent study was conducted by the University of Minnesota which found that atheists ranked lower than “Muslims, recent immigrants, gays and lesbians and other minority groups in ‘sharing their vision of American society.’ Atheists are also the minority group most Americans are least willing to allow their children to marry.”
Great, there go all my dreams of making a difference from the inside by holding a high-ranking political office and settling down with a functional, nuclear family.
