I don't like labeling a man as a racist based on a couple of quotes that the media ran with. The fact that his teammates defended him from that accusation also complicates things somewhat.
But, the things he said in those voice mails to Jonathan Martin are vile and impossible to misinterpret. If Richie Incognito is not a racist, then he was doing a very good impression of one.
Richie Incognito is not racist, he just does not show the typical compassion that other people feel toward one another. I believe he does need some proper counseling and sensitivity training and needs to understand where to draw the line. He still is supportive of his team mates and I think he is slowly realizes what his words and actions have caused.
