In my personal experience it really depend on what you are trying to build but most of the time it ends in the party/collective/space expelling the person from it. What can make this process less dramatic and damaging is the organizational culture you have in the space or the party. For example, in the organization that i´m part of when we reunite, all men are required to help in some domestic(cleaning, cooking or preparing the room for the meeting) and organizing(taking notes on the meeting/discussion, being the mediator of the meeting/discussion[1] and so on) task because we have perceived that this is a way to make the woman in the organization participate more actively in the discussions and we as an organization want them to participate more on these discussions. So we have a culture of doing that and for some time it has been a self-reinforcing thing. So if i stopped doing it, my comrades would call my attention to it and if i really took a stand against it, i would probably be kicked out of the organization. My hypothetical exit would galvanize no one because we have been doing this specific thing for a long time and everybody agrees that we should keep doing it.
In short: I don´t have a definitive answer but a good guess would be organizational culture. We, humans are very social species and take a lot of cues from the people around us and if we are able to create a good organizational culture in a space/party/collective people will mostly follow it. That said,it is hard to create a good organizational culture, people in the org or the space really need to want to make it happen but once it is create it is easier(or less harder) to keep.

Exactly. He will keep doing whatever he wants until he gets arrested or impeached, two things that are super hard to happen. He is in this moment very much above the law.
