Many Democrats are Christians, but they have this "I'm a Christian, so is my neighbor, but that one guy down the street isn't, so everyone has to pretend no one is Christian attitude."
No. Democrats would say, let's not stick a large cross on our lawn that says "Jesus is THE GREATEST" and tell that non-Christian neighbor that Christianity is the best religion. It is called being polite and courteous, something I'm sure you have no experience with. You can be a Christian and go to Church and believe in all the Christian prinicples, while not blaring it out to everyone who passes by, especially people who'd be offended by it.
