Replying to ....why does youtube even allow comments?

It just dawned on me...why does youtube even have a comments section?

Honestly, I started going through random videos, and failed to see a single comment that was intelligent in any way. A lot was racist, hate filled arguing. And the rest were those stupid trend comments like "mom, i have to go kill 50 people who dislike a video...but it's ok, because i have 500 people on my side." or any generic anti-bieber or thumbs up comment.


i feel like it severely degrades youtube's reputation, even though it's the users doing it, so whats the point?
