I was fascinated to see this post of a piercingly insightful breakdown of how it is on a day-to-day basis that movements "for a good cause" can become toxic and unproductive, and what specific patterns of thought to watch out for in yourself in order to make sure you're still working for good and not just becoming self-serving and congratulatory and hostile to other people working for good if they don't exactly fit in your little mold, and ultimately kill the movement... and then the guy posting it saying he doesn't know any other way to be.
Huey said it a lot better, in a positive sense, how to be the positive side, I think. I like this post quite a lot.
