Watched the fights on Sportsnet so didn't have to put up with any silly censorship.
It's easy as a fan to sit back and say cutting away from offensive gestures is irritating and annoying.
You don't have to deal with the flak from showing the gestures.
However, the reality is FOX is a public network and if Janet Jackson's nipple peaking out for a nanosecond resulted in a flood of complaints you can be sure Nick Diaz flipping off Henderson would have done the same.
If you're an exec at FOX you have to concern yourself with more than just what might annoy some fans I'm afraid.
Politically correct? Yep, but that is the world we live in.
