Most alternative video platforms except peertube are crawling with Nazis and antivaxxer. Odyssey, Rumble, Bitchute...

Basically that's what happens when you make a point of absolute freedom of speech... You get all the people noone else wants to touch.

Platforms that may want no affiliation but don't censor enough (sometimes nothing, sometimes only reported actually illegal things) usually end up becoming nazi platforms. (see the punk bar parable)
I don't think Odysee is as bad as Bitchute yet, but my hopes for it becoming good are zero.
