I don’t know how anyone thought this was a good idea for a video.
The dumber and more infuriating a video is, the higher the chance that viewers will start arguing with each other and/or the creator, and share links offsite to show others just HOW dumb and infuriating the video is. It’s the entire point of Rage Bait to be as obnoxious as possible to make people interact with the video in one way or another, because the creator gets “paid per click” in ad revenue. It doesn’t matter to those people whether the comments are actually civil discussions or literally every youtuber just commented “f- you!”, because both are worth one click = same amount of cash. Sharing links offsite is free advertisement on top of that.
Long story short, it is deliberate. And the best way to deal with those is to report and ignore them.
