I'm surprised I know this, but the reason for all this shit on YouTube is the ultimate punchline to the joke that is the lives of these people
Basically it boils down to this Juggalo Holocaust thing which essentially started as a brilliant troll. Someone made an anti-Juggalo forum or something as a joke and suggested that people actually commit acts of violence against ICP fans and specifically target them for all kinds of shit but it was all fake just to troll the hell out of them, and as you can see, it's working masterfully on both ends of the spectrum.
