It should be noted that a very huge chunk of the userbase here are chronically online far left types who were banned from Reddit for being too extreme and toxic. Those same people came over here and brought the same problems that got them banned on other platforms here. Lemmy's is basically a cesspool of the Internets worst leftists.

That being said, I would say something like 40% of Lemmy's userbase is here for tech, privacy, and memes. If you filter out most of the politics, this site still has a big enough userbase to have an active and enjoyable experience.
