I realize that others aren't likely to change just because I want them to, so learning to control my anger is important. Not because it's the "right thing to do" or because I owe them any compassion, but because my health is important to me and I owe myself relief. I think it's reasonable for me to get angry in the first place, though. I think it's natural to be fearful and anxious upon realizing that other members of your species are completely effing clueless. Ignorance can be dangerous.
