The stupidity of Youtube comments is why I tend to agree with channels that disable comments, simply because I can only read so much stupid before my eyes roll into my skull permanently.
Oh, and dare I would say, Jojokes/memes/shitposts videos. At least no one really pretended to be 'in the know' like these Nu-Fallouts fans who agreed with the likes of MatPat despite the guy saying Bethesda made Fallout.
