Irrespective of how justifiable the anger is, the root issue that compulsive anger is both poisonous to mental health and that it gets in the way of critical thinking in ways that make it easy to be manipulated are both true.

Things don't need to be morally equivalent to have the same mental, emotional, and physiological effects. It is also possible to be mad about stuff and take productive action on them without regularly having to stoke the outrage fires. In fact that's critical to being able to think strategically about it.
