The one that started our conversation about socialism vs volunteerism. You've made it several times.
You often hide behind "comprehension" accusations in discussions. OK. Treat me like the idiot you claim I am. The study you responded to says that conservatives are more charitable than liberals. You said that that is explained by conservatives being religious. You've claimed that that comment wasn't discounting that religious charity is actually charity, just a difference in motive (which is inherent by the way, and needs not be stated).
So, your argument is literally an agreement that conservatives are more charitable than liberals and that religious motives produce more charitable people. So, unless you'd like to argue that religious charity isn't charity, that's where we are.
Condescend yourself and explain to the board what I'm missing.
