In the OP's post,it was made clear that the "friend" did not approve of "alphabet kids" in the military as well as the VA spending on Trans care for Vets. That is plain wrong ! Telling this person why they are on the wrong side of the issue is the right thing to do. There is such thing as replacing the term "friend" for "someone I know" after you realize they "will never get it and don't care to". The OP does not have a true friend in this person because she will or may never be accepted for what she may be.
