Is anyone else embarrassed by the fans, or does Kyrie "deserve it"?
I don't know if embarrassed is the right word but I am not defending any fan that shouts obscenities at players during the game. Those fans are violating the stadium conduct rules and making it unpleasant for other fans. At some point, those fans absolutely should be removed by security.
As to Kyrie, I do feel he deserves some level of heckling from fans. I have no problem with fans doing this so long as they hold to the line of conduct (admittedly a very gray, squishy, line). That is the problem though, the line for acceptable fan conduct is difficult to define and even harder for security to enforce.
I do not grant any leeway to Kyrie though for what he did on the court. He is a professional athlete, paid millions to deal with it, and he did not deal with it properly. He is over the line and in this case, it is not a gray or squishy line. His actions are entirely unacceptable with no excuse or "yeah but" or anything.
