I do feel there would be less violation of church and state, but I do also feel religious people would suffer losses of rights we now have. Although, I can't really decide if that's a bad thing or not.
Could they do any worse? No. No, they couldn't. At least I would not have their religious crap shoved down my throat. That would be a bonus. I have no issues worshipping my God on my time, in my space.
