The church as an institution donated money to an organization that was supporting prop 8. About 50% of the organizations total received donations in fact. I am not aware of another source of money that the church receives other than tithing. I suppose the money could have came from the churches investments but the money for the investments came from tithing.
I think I knew that but wasn't thinking about it at the time. My original point remains. We sustain our leaders to lead and manage the church and its affairs. So if we believe that they our not using the churches money appropriately or in accordance with heavenly fathers will, you should not sustain them at the next general conference. Personally I don't think it was inappropriate to use money from any source in this way, I'm just trying to play devils advocate so to speak.
