there is A LOT of things that I don't like in youtube, not only from comments, but from what vids do as well, I'll just list them off so I can vent off:
-People who are trying to correct Facts
-people who asks to go see their youtube channel
-people who hates because they were lead to hate from some other source, (exemple:Screwattack and Marzgurl sent their fanbase to dislike this: A good song, in my opinion)
-people who are trying to defend something even tough there IS NO WAY to defend it(I'm looking at you Ron Paul supporters)
-AMVs (I'm just trying to watch some clips of a show to see if I want to buy the DVDs but then I click on one of these and it wastes my time and everyone's time
-videos that are actively misinforming people(this one is the perfect example: watch out! you are looking at the Fox news of the internet
that's really all I can think of right now, but I'm glad that this post was made, it felt really good.
