A question for vegans (from a vegan)?

I find myself feeling anger and bitterness at times towards all the people in this world who simply don't care about the ethical treatment of other creatures, the earth, their health and well-being, and the health and well-being of everyone else. I don't like feeling this way because it's essentially the opposite of what being a vegan is about. But the blatant apathy of so many people out there makes my skin crawl. I realize the juvenility of this question, but how do you guys deal with this day in and day out? It's not like everyone out there is completely ignorant. They just don't care. How are you able to be friends with meat eaters who's priorities and values seem to be so contradictory to your own?
