One of the things I like best about Mastodon is that there are far fewer people looking for an excuse to put others down. I mean, other people on Mastodon. Not people in general, particularly if Trump is considered a person.
On Reddit you have to worry about any number of assholes who are just panting with lust to sneer at people and their posts. It's like they have to prop up their egos by putting others down. There's some of that on Lemmy, too. Mastodon, far less so. And of course you can always block or mute those people. But it's a lot less work on Mastodon!
