Some specific examples within lemmy.world that prompted this would be helpful (not a request for you specifically, a general request).
A big problem on reddit is debate-oriented communities aggressively stifling debate and banning people for opinions well within the outside-the-internet window of acceptable discourse. So I can see why lemmy.world would not want to go further down that route if it appeared as if it were beginning to happen. Reddit can semi-tolerate it because there enough users to form niche communities if the big ones are terrible. Lemmy has nowhere near enough people.
Unfortunately t can’t all be (1) or (2) because both extremes are terrible.
What would your policy be for example if someone showed up and started debating on the side of Bad Team politics but doing so politely?
