Not parent commenter; I believe that any sport which looks at gender/sex is undeniably sexist, this includes the Olympic games which are by far the most blatant and prominent examples.
True equality can only be achieved by not considering if someone is a man, woman, or whatever they might want to classify as. Lump everyone together, equal opportunities given, and may the best man as in mankind win.
And no, don't give me "Women will almost always lose!". That is sexist bullshit. Equality is equality, we can't have our cake and eat it too. There is no line to be drawn.
