Bio-male thinks he's a female? Well... no. Biology isn't a matter of choice, boys and girls. This is ultimately a decision for States, and it just may end up that the States which disagree, allowing bio males to compete as females may find populstion shifts of greater proportion than occur due to pure politics. With generational change in parenting, this decision may swing the other way, being a State by State decision, but for now, reason has a level-headed cause settled.
Sorry trannies, but your gender was detrermined at conception. Call it something else, if you must, but gender is binary, or so says science in the cells.* All trillion of them in each of us.
*There are physical anomalies in all of 0.00000007 percent of us, about 3 people per country, worldwide, based on a world population of 8 billion people. And what percentage of that number are serious sports competitors? This amounts to affecting such a small percentage of us, statistically, it is a non-issue. That said, there are those convinced by a headtrip that all the above is an issue. So be it. Not all will agree with the Court decision.
