What a crock of shit.
The coach didn't attack her, or shame her, in fact he wasn't even talking to her.
He was making the point to a ref that in determining the actual impact related to a foul call, due importance should be attached to the relative size of the players.
Yes, he used hyperbole, and he exaggerated, that's part of language. There's nothing to suggest he was trying to be offensive, but I can understand that she might have taken it that way.
taken in context, any sane person would conclude he was referencing her size and strength (issues relevant to a foul call.) Not calling her fat, which would not be relevant. But again I can understand that somebody who was sensitive about that subject could be offended. He apologised, and that should be it.
By contrast, she's the one that has set out to directly attack the coach. Using offensive language, belittling him, and referring to him as a "little white man." How the fuck is that acceptable.
Good news for Cambage is that when she's finished playing, she'll have a long and successful career as a professional whinger and victim.
