edit:
I just tried this again and not much has changed. Started by viewing Joe Rogan's interview with Elon Musk on a fresh profile. The first suggestion from there is a Jordan Peterson anti-feminist video, from there we get a Jordan Peterson anti-islam video, then "The Suicide of Europe" by PragerU, and from there the floodgates are opened to fear-mongering about "rapefugees". That's less than a dozen clicks on highly related videos to get from Elon Musk smoking weed to videos with an overtly racist agenda, on a profile that's never sought out that kind of content previously.
