Why is there such a vocal Fan Dumb for other online groups, that promotes the "theory" that you can't like more than one big group on the web?
It's the Internet. It's full of Insane Troll Logic that people think actually makes sense. It's the same reason for pretty much every Fandom Rivalry ever, with the basis of the argument usually being "X isn't funny! Y is!" despite everyone having their own opinion of X, Y, and whatever else there is.
Consider that if a group of people are eliminated from the Gauntlet, they are never seen again. Also consider how Ryan jokes that Murder Is the Best Solution...
