A long time ago, every comment on YouTube was vitriol. It didn't matter what the video was, every single comment was pure poison. Today you can safely read the comments on videos that don't have political context. Of course anything political is going to be completely overrun with state level astroturfing, extremists, and mouth breathers. Occasionally I'll accidentally read the comments on something political, forgetting that comments should be off-limits for that video.
You should see the shit Microsoft pulls with MSNBC. Editorialized headlines, and direct comments sections. It's pure toxic garbage, and they jam it down boomer throats by making it the default landing page in Edge (and IE) and that stupid "news and interests" spot on the taskbar that you have to disable.
This being the same company that got themselves into an antitrust lawsuit for bundling IE with Windows 20 years ago. Fucking bonkers how horribly times have changed.
