This is all very weird. I am always amazed at what dumb things some stars like KD will do. Context matters though.
I played high school basketball in a small town in NH. Back in those days, white shorts and socks were the norm. I was teased about how pale I was. They called me Casper (after the ghost). Comments about being pale just aren't the same thing as comments about being dark or brown or whatever. For me, it truly was just boys being boys.
I don't feel I really understand the full context that KD's comments were made in so I can't really judge them beyond it being clear that it is really dumb for someone like him to put these comments out there, even if the intent was "all in fun" or whatever.
