The biggest threat in America, in my opinion, continues to be American Christians, those driven by fairy tales instead of logic and reason. What’s really tragic is that so many Christians (or at least they appear to be) have moved into the LGBT fight for equal rights. How are we using our brains when we have so many people at the forefront of the battle who don’t even deal in reality? But that’s an entirely different discussion. As for Christians in general, and all people "of faith", these are my two favorite people to discuss it, Bill Maher and Sam Harris.
