Some people, not so much you, but people in general who are uncomfortable with the larger sexual identity issues prefer to focus on the woman's sport's angle because its comfortingly simple and avoids the things that make people uncomfortable.
Maya didn't have her contract renewed because she said things like the senior director of Credit Suisse was "a man who likes to express himself part of the week by wearing a dress"
Not for advocating for fairness in woman's sports.
To be clear as far as athletics. Trans people make up 0.5% of the population. The female->male portion is most apt to experience on average a measurable disadvantage while the male->female portion if they start hormones when it is medically advisable to do so wont experience the same clear average advantage as a male athlete who simply declared himself a female one day and switched teams.

From the British Journal of Sports Medicine
> “For the Olympic level, the elite level, I'd say probably two years is more realistic than one year,” said the study's lead author, Dr. Timothy Roberts, a pediatrician and the director of the adolescent medicine training program at Children's Mercy Hospital in Kansas City, Missouri. “At one year, the trans women on average still have an advantage over the cis women," he said, referring to cisgender, or nontransgender, women.
> For the first two years after starting hormones, the trans women in their review were able to do 10 percent more pushups and 6 percent more situps than their cisgender female counterparts. After two years, Roberts told NBC News, “they were fairly equivalent to the cisgender women.”
It's a tempest in a teapot. All things being equal you are likely to end up with a small percentage of woman's athletics being trans women and nothing else changes. This is especially true of school athletics which are after all supposed to be for the betterment of the student body as opposed to for objective success.
