I have yet to encounter an intelligent person on YouTube. If you view my comments, you'll see that this still holds true. Especially user "humanswin", who believes that a camera flash reflection in a U.S. president's eye and a shutter sound in the background is irrefutable proof that he is a shapeshifting reptilian creature. He goes on to prove this theory by ignoring common sense rationale and blocking users who he/she cannot contend with mentally if they disagree with him/her, such as myself.
I also enjoy pissing people off on YouTube because as stated above, I have yet to find an intelligent person and dumb people are the most entertaining when angry.
