Just because one is transgendered or trans-curious does not mean one is so “confused” that one betrays classified information. I sincerely doubt Manning suddenly confused his flashdrive of classified material for Wikileaks with a wand of mascara.
I personally know transgendered people in sensitive positions, highly-responsible positions, serious-pressue positions, in various walks of like. One’s sexual and gender identities have absolutely nothing to do with one’s work and one’s moral compass.
This is clearly a(n offensive) attempt to play the politically-correct rules game so Manning gets protective custody in prison, since he will probably be executed as a traitor by the other inmates.
