I live in the UK and never see ANY right wing stuff, even though we have our fair share of xenophobic nutjobs (some of them are even running our government’s immigration department currently).
But I’ve heard that some places in the USA may be extremely polarised regionally, and so maybe that coupled with your other demographic information such as gender, age, occupation, etc, might be giving YouTube the idea that you probably fit the standard local mould for a right winger and thus might appreciate the same suggestions?
That’s been my best guess whenever I see this kinda thing mentioned, though honestly it’s just a guess! It always seems to be USA people suffering from it too :-(
Maybe the laws against hate speech, disinformation, etc, aren’t as tight there and YouTube doesn’t have as much incentive to hide that content? That seems less likely, but who knows! When I lived in the USA I saw soooo much more blatant flagrant lies in official emails, ads, media content and such, it seemed acceptable in a way it’s not here.
