I get it, but if being here isn't an enjoyable experience for you, then find a place that is. And I'm not being a dick here.
There have been a number of fangroups that I have been a part of that stopped being enjoyable to me because voices that had similar viewpoints to mine were constantly silenced. But complaining about it wouldn't have done me any good. When it got to the point that that bothered me enough that it wasn't fun being there anymore, I left and found groups that naturally respected all opinions more, were differently moderated, or, worse case scenario, were made up of people whose viewpoints are more similar to my own.
The last solution isn't ideal, but I find myself being a better person in those groups than I was when I countered the toxicity of others with my own because I'm not fighting everyone to get my voice heard.
Again, do what you feel is best, and I do appreciate the different viewpoints conservative posters bring, but do what makes you happiest. And if being here doesn't bring you peace, there are other places that will.
