Why not just let these hippy granola crunchers live in their little bubble of smugness. The pitiful amount of taxes diverted is probably not even worth worrying about. Let them put a check mark in a little box and feel completely free of responsibility. Mennonites, who I find pretty cool, actually need this. Let them not have to live with the moral ambiguity of real life. I have big shoulders and chose this job knowing I wouldn't always be popular.
