Actually I think all churches should have to pay property taxes and sales tax. They shouldn't get a free ride just because they're a religion. Just think of how much tax revenue we could raise from all these multi-million dollar megachurches out there. In return, preachers will be allowed to preach politics from the pulpit if they want (like many of them already do and get away with it). But religion would still be kept out of government as per the First Amendment.
Christian apologetics is the art of rolling a dog turd in sugar and selling it as a donut.
