I have a saved screenshot of when I was watching gaming videos (XCOM2) and all the recommendations were also XCOM2 videos .. and a live stream of UK far-right rabble-rouser Tommy Robinson.

I suspect (but of course can't prove without secret youtube data) that there's enough of a crossover between gaming and the far right that any gamer will eventually see far right videos, far more likely than they will be shown "far left" videos (these must exist, but I've no idea who they might be?)
