No, that's not what I was suggesting. Rather, let the churches collect from their constituents whatever the people wish to donate, rather than as a tax. Having the government collect the tax FOR the churches seems rather archaic. A holdover of the feudal system, perhaps?
But forcing people to pay to attend a church? That just doesn't seem right. You either pay because you believe, and believe it is right for you to pay, or you don't pay at all. This seems to me to be a way to make certain that the churches collect enough money to keep from going bankrupt. Unless you do the same for other businesses it just seems wrong.And letting everybody, rich and poor alike, pay the same total amount is considered unfair, so said tax information is needed.
