Sex exists! You can make cosmetic changes to your body but you cannot fundamentally change the biology. There are times when this matters, and fair competitions of strength and speed are one of them!
Precisely. Cosmetic changes - so choosing to identify as a different gender - all come from a social construct of what each sex should do/act like due to gender assigned to sex (iyswim?)
It reinforces gender stereotypes.
Those with GD who make a physical change to their sex through medication and surgery will stay have had the hormone changes for the sec they were born into.
I find it astonishing that if a female or male athlete took a testosterone based drug to enhance performance they'd be banned for doping.
Yet a man who has grown and developed via the testosterone hormone can compete against woman because they say they identify as one.
There has to be a limit. People should be able to be and say who they want to be. But not at the detriment to another group. Trans woman should not be allowed to disadvantage born woman to advantage themselves.
