It feels like forever ago, but last season there was a fan suspended for calling DeMarcus Cousins the N word.

It sounds like the kid was a punk, but there wasn’t a single witness who heard anything racial.
Or there were witnesses and no one wanted to get involved. And the same thing could have happened to Smart. People could have witnessed it and didn't want to get involved.
I can understand if someone is using their relative's or their friend's season tickets not wanting to rock the boat and get involved in a racial issue that could cause problems for the seat's season ticket holder.
Many black athlete's have complained about racial slurs thrown their way in Boston. I have heard it at Celtics, Bruins and Red Sox games. I am sure many others have as well. The worst I ever heard was stuff thrown P.K. Suban's way during a Bruins playoff game. It was alarming.
But, my guess is, and recent events in NY and Utah confirm this, that racist remarks towards players happen everywhere. I don't think Boston has any more or less racism than other large cities. It exists everywhere and I think racists, in general, have felt more empowered to be overt in their racism given recent national events over the last 4 years.
The worst racism I have seen and heard happened in Florida, Texas, Vermont and New Hampshire. But as I said, it's everywhere and that's unfortunate for this country. And I am not sure it's going away anytime soon.
The movie Bulworth had a great idea to end racism....everyone have sex with everyone until we're all the same color. Always thought that hysterical and very apt.
