Part of me hates this part of me understands.  The military should certainly not be required to pay for sex change operations.  And if you can be 86'ed for not having proper vision or for having some other chronic physical condition, then why would changing your sex not be a a huge psychological/physical  barrier ?  But if you have completely transitioned then why should it be a barrier to serving in your military ? It is done, fixed as the case may be. If you had a broken leg growing up and it is long repaired then it is no longer an issue right ?
