Get this through your thick head, nitwit, but there is something called "freedom of speech".
That means that this guy gets to say that he doesn't like female commentators without you pulling out the "sexist" cards.
That is NOT what freedom of speech means. That means he can say whatever he wants without it breaking the law. Anyone else is still perfectly entitled to make any judgement they want, and in this case - it's the correct one.
Not liking a female commentator is absolutely fine. Saying that you don't like a commentator solely because they are a woman is sexist and has absolutely no place in modern-day society.
