Sure, you find disagreements and arguments, but you don't get the 'ur mum gae', the reductio ad Hitlerum, the dongers, and the outright insane takes and paragraphs of all caps that I would expect from Youtube comments. Meanwhile, every time I open Facebook because of some event I need to press 'going' on, I get a glimpse of some inane take or someone writing in all caps because reasons.
There have been a few waves of comment spam, but maybe Youtube actually managed to curb that now? Only took them two or so years.
