Churches don't pay property taxes or income taxes. Clergy often get free housing they don't pay taxes on even if they do pay taxes on their income from the Church. We provide police and fire protection to church properties through our property taxes, how is that not subsidizing them?

I think there are a great many of those 501 c corporations that should be looked into as being a racket. As for religious organizations one of the IRS allowed charitable activities is "advancement of religion", Churches get tax free money to promote themselves, how is that not subsidizing them?

Not only aren't the churches paying income taxes, we're not collecting taxes on the money before it is donated to them. This subsidy may be costing us hundreds of billions annually. Due to restrictions placed on the ability of the IRS to audit churches we'll probably will never know how much the scammers are costing us. 

Religious rites should not be a part of official government proceedings. Incl'd invocations.
