I was thinking the same thing. Reddit is a cesspool because communities shut out anyone who dissents with a group's opinions, allowing the group to continue thinking "everyone" believes the same thing they do. Sure it's a good thing for mods to be able to quickly block obvious troublemakers, but there needs to be an unbiased review process in place when someone is kicked out simply for disagreeing or asking legitimate questions. Echo chambers are bad.
Telling someone they're disgusting for being POC or LGBT+ is a good example of an action that deserves an immediate ban. Asking someone what policies a political figure implemented that benefited you should NOT be a reason for a ban, especially if you're only banning them because you can't answer the question.
I'm not quite sure how the process works on Lemmy, but I feel like moderation should include incremental periods. Like the first time you get blocked for a day, then a week, then a month, and finally a permanent ban. And a person should be able to request a review of their ban, which would be judged by a panel of mods from random groups and instances to limit people of like minds all piling on for the same butt-hurt feelings. There should be ways to make things more fair than just reddit's policy of an invisible admin making decisions based on their mood that day.
I wonder how long before they just roll this into the yearly flu vaccine? It doesn't seem like something that is ever going away until all the anti-vaxxers die.
