Isn't that basically the whole point of the algorithm? Isn't it behaving exactly as advertised?

You don't even have to feed the algorithm to get those videos. I have my history turned of so I don't get any suggestions on my home page anymore, but when I'm watching a video, the suggestions on the side invariably have a handful of right-wing idiots. You can sometimes see how YT might think they're related to what I'm watching (usually retro tech stuff), but they never actually are. I rarely see the same misfires with the left-wing videos. My guess is the brain-dead right-leaning viewers put that content in the high engagement buckets so they just get suggested more often. I don't think left leaning people engage much with the left wing media because it's usually boring politics that don't infringe on basic human rights, and we already know how bad the right is just by seeing them suck with our own eyes, we don't need to be told about it over and over to believe it, or to get bullshit "gottcha" material for water cooler conversations. We also already see how the politicians on the left suck in their own special ways without needing anyone to explain it to us. So what's the point in investing in a video when a few words, or none at all, will do the trick? Algorithms target idiots with unfounded rage, it's just that simple, I wouldn't even call it an algorithm, just basic number crunching.
