I once knew a local "activist" who frequently weaponized leftist language in order to police or punish other people. Ie, accusing people of racism for ordering an Asian Chicken Salad at a fast food place, or for trying to learn Spanish at the community college, and she would phrase her criticisms in such a way that any complaint would make the other person seem wrong. I legitimately thought she was just mentally ill.

I found out later that she was trying to blackmail and defraud a local charity, and that's when our association ended. She has been banned form some community organizing spaces because she inserts herself into every single one of them.
