The OP posted "*he" as a "correction" for a "she" talking about Chelsea Manning, and seems to have been offended they got downvoted.
Apparently they may not be familiar with the difficulty of assigning gender. The least politically charged way to seeing this is to look at Olympic sports, and https://www.buzzfeed.com/azeenghorayshi/sex-testing-olympian... is a good overview.
I'd draw particular attention to the case of Ewa Klobukowska who was stripped of an Olympic Gold medal for "failing a chromosome test" (ie, exactly what the OP is claiming should be the arbitrator of gender).
https://en.wikipedia.org/wiki/Maria_Jos%C3%A9_Mart%C3%ADnez-... is another case.
Ewa Klobukowska later had a son, and had her medals returned.
