https://lemmy.world and https://kbin.social are federated alternatives to reddit. Many of the same communities exist there and there is robust debate. I like the kbin UI better, but Lemmy seems to work better.

Trying to sign up for lemmy.world for a week without success. But happy on https://lemmy.one. It doesn't have downvotes, which for me is a big plus!
