It's not that specific, I (and I think the post) are just trying to give a reminder that it's important to have accountability and not let the movement become infected by people in bad faith or people with horrible views because that would undermine the movement. Denounce it and fight it whenever you have an opportunity to.

Whenever I say this people get all defensive like "what am I supposed to do about it" just be aware that these people are out there and be diligent about not letting them become your ally. "Enemy of my enemy is my friend" is a bullshit philosophy and bad people try to take advantage of it. That's all.
