No trust me, the majority may hate him, but on a heavy American board there is much, much more hate. Seriously maybe 70% hate him here? He is pushing 90% on American boards. The guy is one of the easiest in the sport to root against.
Bisping is the perfect "bad guy" for the Americans: English, confident (see cockey if you're American) and almost always wins (13-4 with only 1 clean loss).
The only guy who i think got more hate than Bisping was Paul Daley who since leaving the UFC is not really in the firing line - i sense Daley is hated for the same reasons as Bisping except with the added bonus of being black.
After Bisping TKOs Belfort i hope he wipes his arse with the American flag as thousands of Brazilians cheer him on (joke)
