Youtube comments can be really memey, too. Go onto a popular youtuber's video, take for example Game Grumps, and you'll find people constantly spewing outdated and overused memes in the comments with thousands of likes. I guarantee you you will never be able to find any sort of quality discussion on one of their videos, period. Of course, then there's the incredibly unhinged and edgy people who spew those insults. Stuff like that is why I avoid any popular youtubers.
