>Right wing subs are just as bad, the only real difference is who is the majority. Is there one right wing subreddit that uses preemptive bans? There are numerous left wing subs that do this, even though they already completely dominate the narrative on reddit.

Left wing subreddits are faaaaaar more heavily censored. It's not even debatable. There are no conservative subs that will ban you before you even make a post. The left doesn't even need to censor since they completely dominate reddit, they just can't stand the idea of conservatives being allowed to speak. Even on a higher level, admins will invent reasons to shut down conservative subs but, but left wing subreddits have free reign to do whatever they want, including worshiping genocidal dictators or mass brigading wrongthink subs.
