I know what you mean. But pronouns which relate to social gender can be differentiated from sex/biological gender.

To rewrite your original comment, "Lia Thomas, who was born male, was permitted to compete on the basis of her gender identity claims" would be a fine and understandable statement, I think.

When talking about the person Lia Thomas, we are talking about a woman. She's Lia Thomas. Yes, she was assigned male at birth and her biological gender is male, but the person is female.

Again, I am maybe a bit petty, but I think this is exactly one of these important aspects when talking about transsexuality.

I'm not really disagreeing with what you're essentially saying, just trying to make a point about transsexuality.
