[context: Do you want government mandated religion?]
1) What do you say/do/feel for minority religious people? I'm sure there are a significant number of devout people who find objection to any but the most mundane religious prayer/symbol/etc. Maybe consider a Catholic parent who's offended that that Ten Commandments imposed on schools is wrongly stated from the Catholic point of view.
A vote should be held on this. That's why we have school board elections, mayoral elections, etc. If you object to a Protestant being elected mayor, you're welcome to elect a Catholic. That's what "no religious test for office" should mean.
2) What do you do when Christian's differ in their faith? At least in my home town, the majority of Churches are super open to, and encourage the membership of gay people. But some churches disagree. Yet we probably need a state or national view on "Are these two particular people married".
A vote should be held on this as well, of course. That's why we have a democracy. We held votes on it, the American people agreed that marriage was only a man and a woman, it should have ended there with no issue.
P.S. There is one majority Muslim town in the US with 25,000 people who live in Hamtramck MI.
They should have been deported.
