Does the DoD hate diabetics?  Or drug addicts? Or hemophiliacs?  Or people with HIV? How about Multiple Sclerosis?  Or Muscular Distrophy?  Or Schizophrenia. Or Spina Bifida? All of these are disqualifying medical conditions for enlistment.  A person so disturbed by the difference between their biological sex and the one they wish they had that they would seek surgery and hormone treatments to look like the other sex is clearly mentally disturbed.  And shouldn't be seeking the taxpayer to pay for their delusions.
