The one group of Americans our media is still very comfortable making fun of is poor, white, uneducated Southerners. Bonus laughs if you make them Bible thumpers!
Making fun of blacks is certainly not acceptable anymore. Big-chested blonde bimbos are no longer funny. Mexican sidekicks have run their course. It's still okay to laugh at gays---but nowhere near as okay as it is to laugh at hayseed ignoramuses.
And now we have Bruno, an outrageously gay man making fun of hayseed ignoramuses! Can you spell surefire media frenzy?! Not if you're from the South!
Isn't it great that so many other people are uneducated, spiritually immature, racist homophobes?
Without them, who would be left to laugh at?
