A lot of real-life communities restrict discussions about politics too...
I assume so because those discussions easily lead to fights 🤔 I think many communities just want the good vibes and not risk dealing with bad behavior or fighting or whatever other negativities these kinds of topics can bring.
but because I think those communities challenge my worldview more
I feel there's a difference between questioning your beliefs or points of views in a constructive way to make you think more and articulate your reasoning behind them, questioning them in a negative feedback without bringing anything positive or "developing" to the discussion, and then just trolling or doing anything just to start fights.
