Keep it out of the government HOW, though? That is the crucial questions. You can't keep politicians from voting their consciences, nor can you keep them from displaying their beliefs publicly. Those behaviors are absolutely protected by the 1st Amendment. I think it would be more effective to take as much power away from the government as we can, and leave it to do things that have nothing to do with personal morality.
Exactly. If it weren't in the state's power to enact laws prohibiting certain substances, curtailing reproductive rights, censoring certain speech all because it offends their religious morals I wouldn't care. Politicians could go on and on about god all they want and I wouldn't care because they wouldn't be able to do anything. But as it is in their power to do those things I have a problem with allowing religion near the government.
