Whoa! I think you might want to wonder on over to DU.
Churches are supported by concrete foundations (generally speaking).
Generally they get built and attended by people (who do pay taxes).
Occasionally (not as often as should be the case) they perform some pretty significant functions for the rest of the tax payers (such as feeding the hungry, clothing the nekid, housing the homeless, that sort of thing).
In those (admittedly a little too rare) instances that they do those things, they do it much better than the institutions which ARE supported by TAX dollars. And they do them WITHOUT tax dollars, but rather the donations from those tax payers who are too stupid and mindless to know that there is no GOD, and are tricked into donating their money for such purposes.
Uh, if one speaks the truth here, they are pointed to the DU? hmmmm.
I think I hit a sore point ...
Churches are no longer holy places. They are now businesses paying outrageous salaries to the pastors that go to the highest bidder. The church buys the "pastor" inorder to be able to recruit more members and their donations.
