The same is true for people in their '50s and '60s.
Same here. I go back to the days of Usenet in the mid-1980s. I couldn't even tell you all the different online forums I've belonged to after that. Well, even back in the '80s there were email lists, too.
There were lots of BBSes, LiveJournal, a blog I started in the early days of my RPG site, Facebook 🤮, DreamWidth, Reddit, and I can't even remember how many other social media sites. They all basically turned fascist and had very toxic environments, except for DreamWidth and Mastodon.
