There's no scarcity of hate on Lemmy either. It simply flies under the radar for most part because it's directed at things we hate too. Exactly as is the case on far-right forums as well. Just read the comments of any thread about Elon, Police, Ai, Facebook, Twitter, Capitalism, Israel and so on. You even admit participating in it yourself.
The far-right thinks of themselves as well meaning just as well. Nobody thinks of themselves as the bad guys. Claiming they intend to be hateful and evil is disingenuine. That's only how you view them. Their view of us is hardly any different. Both views are wrong.
