I think I'm very lucky the writing communities I joined barely ever talk about politics. I was part of other communities with a section specifically for politics. That section was always the most active, even when the main purpose of the community was vastly different, and theu'd even apply those politics directly on the community. Most of the time I had to stay shut, it seems like the whole section was about roasting Trump and any other republican. However, there were times I couldn't stay shut. One time I said there were only two genders and I almost got banned from the community (ebded receiving only a warning), while someone else who also argued with me ended indefinitely banned. The other time they decided to ban a word directly attached to the community just because some people were uncomfortable, meaning no one could use a certain word that was used frequently in the past 10 years. Whoever argued against it, including me, got harassed by the other community members. Those were not the only times, I know I have been a lot of times harassed for expressing a different viewpoint.

Again, I am glad I didn't have to go through this in a writing community. It must be really demotivating being met with that kind of harassment from people who otherwise share the same principles. I know I have seen writing communities who had a thing against Lovecraft for his history on nazi. I completely don't share his views either, but I understand he's a person from a different time and has different fears, and that's what makes his works great, right? I feel like the SJW writers forget the most important thing about being a writer: being open to many ideas, ways of viewing the world and feeling the world. They want to be as woke as possible but they forget even the people they deem villains are human beings with fears and desires.

I believe that the fact you're here, acknowledging where it went to far, already gives you a better potential to be a writer. I hope you can return to writing and feel more open to express your way of viewing the world. You have your own fears and desires, you can definitely work woth them.
