Except not ONE black dude on his team or even in the NFL has come out against him using that word. Like you pointed out, he has even been called an "honorary black man" by his black team mates.
The whole thing that got Incognito in trouble with most of the general public is that he dropped the "N" word when going after Martin. Without that, most of the general public laughs Martin off as a sissy. I get the impression from Incognito that he is the type of guy who would crack the skull of any white man on an opposing team who is phucking with any of his black teammates. Could he still be a racist? Absolutely, but I think what happened here is anything but a racist incident.
It's okay white people, they gave us the go-ahead, we can stop acting like we're offended by this now.
