You agree with non-females competing against females?
This is not a slippery slope issue. Its a basic category-definition issue.
I found this picture of her and her wife interesting -- in that if she looked more "female" the placement of the hand would raise eyebrows.
I was really commenting on aberration of how much testosterone she produced but as more was revealed about her I can say whether or not she is a female.
I do NOT support non-females competing against females.
Her case is not so obvious as the gender fluid males who compete. Who I do not support.
