I don't think UFC fans are bias to Non-American Talent. Its the fact that the fight was in the States, and one of the fighters were not american. I'm sure that if the fight was in Montreal, the reaction from the fans would be complete opposite. Fans are being disrespectful, you can tell by hearing chants of "GSP" during the fight. Its just like watching two countries play football, if you're watching France and Brazil matches, the respectful sides will boo the opposition. Its nothing personal, its just the fact in fan based entertainment events.Its like that and its not going to change. Its been done quite a few times when Canadian fans outright boo the NATIONAL ANTHEM of the states at Hockey games....now that is DISRESPECTFUL. You can boo the team, but never a national anthem...thats just crossing the line. Hopefully that input helped.
And the fans...they were chanting "USA", but when Hughes went down, it was nothing but cheering...FROM EVERYONE, so I don't think there's a bias at all, its just whoever is winning gets the crowd, thats how I see it.
