I said nothing about mental condition of transgendered folks.  I said that serving in the military is not an absolute right, and it isn't.

As for people currently serving, it's important to make sure that every service member is contributing to readiness and cohesiveness and effectiveness. Don't read into this what I'm not saying. I'm not saying that transgendered people are not doing their jobs, I am saying that nothing, including political correctness, should prevent any commander from removing any service members if there is an issue with maintaining readiness and effectiveness.  We've seen this happen with service members known to be sympathizers with terrorists like ISIS.  If a transgender is creating a problem (and again, I'm not being specific, but anyone can create an issue that deserves discharge) they should not be protected just because they are transgender.

And I think if you want to transition to another gender, that should be handled outside the military.
