the same thing applies to vegetarians. Smart and effective vegetarians who want to promote vegetarianism don't fill a balloon with red paint and throw it at someone while screaming 'meat is murder!', they convince people to cut down their consumption, promote alternatives that ordinary people can deal with, and as a result get 50% of what they want to a hundred times as many people, which is more than 100% of nothing.

That's the difference between ideologues and people who actually care about the values they promote rather than people who aggrandize themselves.
