Just looking at the front page of BitChute it seems more conspiracy crazy than just recordings of crazy things happening.
(The name is somewhat amusing for someone with knowledge of Australian slang.)
This may provide Bitchute with some diversity of content. I think this counts as a fringe community just not one that's all American right wingers. It remains to be seen if these communities are compatible (one group calling the other one "sand ****ers" in the comments might be an issue since Bitchute doesn't censor anything).
