Prob because the fucking interviewer asked him the question: "how do you deal with all the haters?" so he answered the fucking question you dumb ass. Jesus if you want to blame anyone for being a douche blame the interviewer for asking such a fucking stupid question.
You yourself said "if he had any sort of head on his shoulders he would of completely ignore the hate" I think the does... The answer to his question of "how do you deal with the haters" started with "I can't worry about what other people think of me," then he said what you quoted. I am just blown away how out of context you took that interview speech, and then criticize him for things he actually did. You are so fucking disillusioned it just blew my mind. And it is harder than you think to not address the "hate" at all, this isn't like some isolated event where it gets no media spotlight, it is talked about very frequently on major networks and it gets a lot of press (the hate of LBJ that is). Difficult to just ignore everything people say about you in a public setting, esp if it could be damaging to your image.
Btw EVERYONE FUCKING WHINES IN THE NBA. Everyone thinks they are fouled, everyone complains, it is what they do. Stop trying to justify that as a reason to hate someone. But please continue to hate away, it is fun and entertaining.
