The news sure makes it sound like Trump hates transgenders, after all he tweeted something about banning them from the military... ahhh but I think people need to read past the headlines. Trump uses Twitter to blow off steam and says lots of things that only hint at whats really going on.
In this case Trump is justifiably upset about the new politically correct cost our military has recently started incurring since Obama changed the rules and allowed those with sexual issues like transgenders to openly server in the military. As things are now a young transgender individual can sign up for a few year hitch and then demand gender reassignment surgery, after they enlist, spend the good part of a year recovering, and cost our military $50,000 to $100,000, just for the surgery. For God sake Obama made signing up for the military the easiest way to get taxpayers to pay transgenders for their surgery including all the time off.
In this case I think Trump might have a point, if you're transgender and want surgery, I think you need to do it on your own, not sign up for the military so you can get the surgery and the time off with full support for free.
