They are because it is easier to dismiss the claims of these players as trivial. Same group of people insist that this is "just because of a t-shirt." Well meaning liberals are also guilty of diluting the message of the Oklahoma State players by calling everyone and everything racist, when this hasn't been the messaging from any of the players, at all.
There are people on this board who I like a lot, who if in the same place as Gundy would probably make the same mistakes he has made. That doesn't make them racist. I don't think Gundy is a racist, he's just a really poor listener who has a hard time relating to people who have cultural differences.
