Outside of our division rivals (it's a toss up whether I despise the Falcons or the Saints more) I've never really bothered to plumb the depths of other teams' fan bases, especially the AFC teams like Denver who we see only occasionally.
But after reading their forum and the comments sections of news articles, damn if Denver doesn't have the most delusional homerism I've seen. They're like the old Chicago Super Fans predicting absurd margins of victory. I'm not even talking about trolls being trolls, I mean just obnoxious and flippant disregard for any aspect of the Carolina Panthers' game.
I hope the Panthers go Conan the Barbarian on them -- "Crush your enemies. See them driven before you. Hear the lamentations of their women."
