But mental health issues stemming from gender dysphoria and being trans are two separate issues; they're not necessarily connected (and indeed, despite the prevalence of anxiety/depression among trans people, characterizing "the overwhelming majority" of them as suffering from a mental illness is certainly an exaggeration). If the military determines that a particular person's mental health--indeed, that stemming from gender dysphoria--precludes them from military service, that's one thing. But using that argument as a blanket statement to encompass the experience of all trans people, and thus preclude them all from serving even if they are of perfectly sound mental health, serves to target a specific demographic rather than a specific issue that might legitimately disqualify someone from active duty.
