Americans don't give a shit about football because they suck at it. They're ego-driven animals. If they found some, even minor success in the sport, they'd start caring. But since they're shit, they cope by claiming it's boring or for poorfags (which is to its merit, not a flaw) or some other lame insult. Meanwhile they play handegg, which is just rugby for women and cowards, and niggerball so they can get their daily dose of black people worship. Both games are 90% commercials btw.
Their only good sports are baseball (nobody cares) and hockey (which they're pretty ok at) but if they sucked ass at hockey you know they'd drop that shit immediately.
