But is that not how communities should operate here? As long as they follow the instance's rules, they get to make a community with their own rules..
If you want to make a community about spongebob memes where people are only allowed to post spongebob memes, you can do that and remove any post that post things which are not spongebob memes..
If conservatives want to create an "echo chamber" where only conservatives are allowed to post/comment, they are just showing that their stated values about "freedom of speech" and "opposition to censorship" are not genuine...
If they want to allow "civil discourse" only to then backpaddle, they will also not look very good..
And this instance's rules are clear, this isn't like reddit back in the day that allowed any post. If people spread transphobia or hate, they get banned, and if we look at other "conservative only" communities on other sites, they probably won't be able to stick to those rules anyway..
