I’d recommend visiting it or joining an instance that federates with it at least. The liberals like to make it out to be a communist propaganda machine but most of the content is memes, oss, and general left wing / anti-US stuff. They will ban you on some communities if you bring up tianemen square or uyghurs though, so that sucks, but otherwise most of the content / users on there are decent.
Man you’re getting worse than the hexbear edgelords who just shit on the liberals all day, except at least they’re yelling at people in power and not some extremely marginal leftists who would be shot before they could ever take a seat in politics.
A good rule of politics is if someone or an ideology that you don’t like and they have no power or connection to power just ignore them, especially if there on your side for 90% of actual relevant issues. Not theoretical issues that may pop up after the revolution that may never come.
