And you think that doesn’t happen in liberal subreddits? I’ve been banned from /politics /News /worldnews all for disagreeing with people. All near instant bans. I’ve even been banned from non political forums because I shared unpopular view points, such as “femisnism has hurt dating dynamics”. Yes that got me banned. So you know full well wrongful and politically motivated bans happen all the time from both sides. So it’s a moot point.

/news and /worldnews are hardly liberal. /news leans pretty conservative on many days.
