No I am not arguing that biological men can be biological women.
Clearly you are, because the only possible way to be a woman is biological. Woman is the word for adult human beings who are female, like queen is for cats and vixen is for foxes. Adult. Human. Female.
And yet you keep trying to crowbar Semenya into womanhood.
CS, IK, BB and all the others brought up in this blind alley discussion are male. Male with DSD conditions that only affect males. How they thought of themselves is irrelevant. They are men and therefore cannot participate in things made for women.
If they try to, they are cheating.
Colour doesn’t come into it.
Side note - Ethnicity/country does have a bearing in practice, because DSDs occur at vastly higher frequencies in populations that have a traditional of families intermarrying. Turkey, North Africa, regions of Southern Africa and Pakistan in particular have higher rates of DSDs
