the video about fediverse and trolls at https://conf.tube/videos/watch/d8c8ed69-79f0-4987-bafe-84c01f38f966 is not bad at all. It demonstrates one of our great strengths, local moderation by people you actually trust. I think the idea that gab left the fediverse because they got blocked by instances like rage.love is the wrong conclusion, but the main points still stand.
Listening to him talking about hate-speech, good moderation and dangerous posts sounds to me even more crazy then expecting 99 perfect virgins after death.
