Take away the tax exemption for churches while you're at it.

I don't find this especially objectionable; it's possible that people (like me) who would donate to charities for animals will now direct our money toward those that help people if we know that the A.S.P.C.A., for example, now has enough money to fund operations for decades. Anyway, it's much more offensive that people get a charitable giving subsidy for donating to horribly bigoted religious charities. Maybe we should just do away with the subsidy entirely.
