I cannot see how any of these quotes relate to Fan Dumb (aka complaining about people you don't like)
For example
I'm glad you are willing to admit how horrible the characters are. I also thank you for showing how much of a hypocrite you are. I shall continue to hate this video and every FF XIII video in existence. When XIII Versus and XV come out, I'll be there to destroy those games and expose them for what they are too. If you don't like it, go find another series to defend. Because I am more of a fan than you shall ever be. Go cry in a corner now and get into a university, jack-ass.

How is this Fan Dumb?
