There are Jews in the world, there are Buddists,
There are Hindus and Mormons and then
There are those that follow Mohammad...
People believe in different stuff. Those beliefs should be subject to scrutiny and disagreement like anything else. We have a great system in this country which lets you worship any way you want, mostly, or not at all. I think it's reasonable to ask people to not be assholes to each other needlessly when it comes to religion, but to the extent that you're bringing your religion out of your home and church and bringing it into the public (and especially political discourse) those ideas should be subject to the same disagreements as anything else. I don't normally care how many Thetans Tom Cruise thinks he has in is head, but if he gets on the teevee and starts talking about it I might make fun of him. If he gets on the teevee and starts telling me that we need to ban anti-depressants and throw psychologists in jail I'm going to fight his political agenda.
