I look at Mastodon once a week, and it all kind of has this same vibe. It's always righteous and reactive. This isn't to say I disagree with the content of the posts, but if you're not a social media regular, it provokes a "why are you talking like this?" reaction.
But I guess that's the function that follows the form of social media. In a way, my reaction makes about as much sense as looking at a karate school and saying, "There's so many individuals here, but I don't understand why you are all doing karate." People on short form social media are doing social media.
