I laughed when I first head about that tweet.
Trump just doesn't give a rat's behind if the loony liberals (what other kind are there) don't like what he's doing. I love that about him. I do say that if people pay their own medical expenses and becomes some other gender than what God made him/her, and has ... oh, i don't know... saved a fellow soldier's life... well, maybe there can be an exception in that case? But then others would be crying to be allowed and how its discriminatory to allow this person but not another and so... yeh, just get them all outa there. It's military, not a social club.
