Religion is a business and should pay taxes like any other ...however, I think if any other business was peddling such falsehoods and a bad product/service with zero evidence of its ability to deliver on its claims at the level religion gets away with they would have been shut down by The Better Business Bureau, making the taxes moot.
Religion is the only industry that produces nothing but fear and misery and sells it for an awful lot of hard cash and free service.
There's no such thing as something for nothing? Tell that to the fricking pope!
