re: #332 Altermite
As of 2008, there are about 34 million people who identify as non-religious. There are an additional 11.8 who did not give a religion, most of whom are believed to identify as nonreligious. Even halving that number gives you 40 million nonreligious people in the US. There are almost 9 million who are adherents to a non-christian faith. Its not a dealbreaker for all of them, nor the only issue, but it is for plenty. Its a huge issue for the jewish community, for example.
80% of Americans are Christians.
