The situation is similar to migration in Europe. People found a not only legal loophole but one which is protected by political correctness. If you speak up against it you get labelled as a shitter.
However there are some cases where careful bending of the rules had some success. A "female" weightlifter lost all her records and titles recently because the lawyers of assblasted women could prove she is still a he.
Since everyone can be whatever they want officially, the rules are usually tie womanhood to testosterone levels which are easy to manipulate. I for one would very much love to see womens sports being dominated by these people just for the keks.
