You already support every church - you pay 20% more in taxes because they pay none for their land, yet demand city services from water, sewer, police protection, fire protection, parking enforcement, etc. They get a free ride. If that land were put to constructive business use, it would generate a huge tax base. Thus, it is 'lost income' that you and I get to make up. ANd we haven't included sales tax, plus all the 'charitable deductions' citizens take on their taxes, meaning others have to pay more to collect the same money which it takes to run the gov't, both when there is local/state income tax,and federally.

And I do not feel churches should be exempt from property taxes, but that's another issue. The original point was that it was unethical to utilze a museum's free day when retired. If it cost the museum too much to offer a free day, they would not offer it. Between that and the fact that most museum's are partially Federally funded (and I do pay taxes still), I have no problems with the "ethics" of utilizing them.
