I may get blasted for my take here, but I just don't see why so many people are deeply offended by this.
First, I certainly don't feel the same way as Sterling, but we've all met plenty of people who have.
If you listen to the tape, nothing on there suggests he is racist. Racism involves beliefs or actions suggesting that one race is superior or inferior than another based simply on their race. It can also imply that races should be treated differently.
He never suggested that White people are better or superior to minorities (Hello.....he was speaking to a minority), or that they should be treated differently. He never suggested that he doesn't want black people to attend Clippers games, he asked her not to associate/publicize her relationships with minorities. Is this idiotic? Yes. But I don't see how it's different from an Indian mother only wanting her son to marry and Indian girl or a strong Black family wanting their son/daughter to marry a black person. Stephen A. Smith once wrote in the Philadelphia Inquirer that his mother virtually demanded that he only marry a black woman. Is this racism? No. I had a "friend" growing up who's parents were Polish immigrants. I could only see him at school because his mom only wanted him to associate with other Polish kids. Is his Mom racist? Maybe, but I can't assume that based off of who she wanted her son to spend time with.
Do I think his comments were ridiculous? Very much so. Some people have a mentality that people should "stick to their own." Sounds like Mr. Sterling has these types of feelings, probably a result of his upbringing. (Although apparently he doesn't think it applies to himself).
Did he suggest not hiring minorities? That minorities are inferior? That minorities should be treated differently by society? No.
If anything, he's tried to overcome his buried prejudices though many positive actions directed towards minorities, as evidenced by his multiple lifetime achievement awards from the NAACP.
Keep in mind that he said these things to someone he trusted and had feelings towards in the privacy of his home. I'm ashamed that the media and society are coming down so hard on this guy. Forcing him to sell his $1 Billion business because of this? That's getting ridiculous.
