I go through stuff like this all the time and honestly, I have no solution to offer.

I feel like every wrong/inaccurate thing a person says is an injustice. Why SHOULD I let it slide? Why shouldn't they have to realize and admit that they're wrong, and how come everyone is so focused on MY anger and MY argumentativeness and not on the initial wrong that was done/spoken/typed in the first place?
I honestly think it's just because I'm the easier target.
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.
