I think some of it is racially driven. We all stereotype. And while that may be a segway into racism, its the way the world is. If you guys on here don't want to admit it, I will.
When Kane cut his hair the way he did, the first thing that popped into my mind was, "That's a stereotypical black youth thing" (which is obviously incorrect and its just a narrow minded thought) It didn't bother me, and I don't care or condemn him for it, I enjoy personality and deviations from the cookie cutter hockey player, but I'm just being honest. I guarantee that 99% of you thought the same thing.
On the flip side when Brian McCabe had a mowhawk thing going (Which is an equally stupid hair cut) on...no one cared. It was just about his play. If a black player decided to get dreadlocks, guarantee people would see an issue with the style.
So while these aren't the most devastating forms of "racism", its still ingrained a little. Don't kid your self Calgary.
BTW I'm a 26 brown guy so i'm allowed to say this
