Not sure why that seems to be.
I do agree with the Republians on this issue. If you have the xy chromosome (Biological Male) then you cannot compete against a person who has the XX chromosomes (Biological Female). The sex chromosomes do not change for a transgendered person. It does not matter how many operations the doctor performs on you.
Bruce/Katelyn Jenner (who won the decathelon in 1976) will always have the XY chromosomes. He/she should not be competing against other bilogical girls.

Take Swyer Syndrome for instance. An instance of a woman with xy chromosome.

Swyer syndrome is a rare disorder characterized by the failure of the sex glands (i.e., testicles or ovaries) to develop. Swyer syndrome is classified as a disorder of sex development (DSD), which encompasses any disorder in which chromosomal, gonadal or anatomic sex development is abnormal. Girls with Swyer syndrome have an XY chromosomal makeup (as boys normally do) instead of an XX chromosomal makeup (as girls normally do). Despite having the XY chromosomal makeup, girls with Swyer syndrome look female and have functional female genitalia and structures including a vagina, uterus and fallopian tubes.
Girls with Swyer syndrome lack sex glands (ovaries). Instead of sex glands, women with Swyer syndrome have “gonadal streaks”, in which the ovaries do not develop properly (aplasia) and are replaced by functionless scar (fibrous) tissue. Because they lack ovaries, girls with Swyer syndrome do not produce sex hormones and will not undergo puberty (unless treated with hormone replacement therapy). Mutations in several different genes are known to cause Swyer syndrome. This condition can occur as the result of a new gene mutation or can be inherited in an autosomal dominant, autosomal recessive, X-linked or Y-linked manner.
I get your point but not every athlete with an xy chromosome has gone under the knife to change their gender.
