I can't believe I'm dignifying your garbage comment with a response, but here goes.
Everyone knew Sterling was a racist creep. He'd take friends in the locker room and point out the beautiful black bodies like he was Jimmy the Greek. And of course people were aware of his legal troubles, which stemmed from discriminatory practices. However, there's a line crossed when someone says "Don't associate in public with black people." That's an explicit, ridiculous statement.
I know you think you're making this critical point that everyone else is missing. You're not. You seem to be the only one not understanding the basic point that he got caught saying something outrageous, something that nobody could look past. Yes, people were digging their head in the sand a little bit. Doc and the players said, we don't like this guy but as long as he doesn't get in our business, we'll tolerate it. He got in their business, and they had to deal with it. As did the NBA.
Get it now? You're welcome.
