Maybe it me, but I am not viewing these protest the same as you and mickey are. I haven't seen any indication of anyone's protesting being directed at the current military or veterans. I was under the impression these protests were about calling attention to perceived unjust domestic actions and policies in the hopes of change.
And because protests are one of our fundamental rights as Americans, I view these protesters as in a way "honoring" our military and veterans, for us all having that right to protest. Agree or disagree with what is being protested, military and veterans should take pride in that they protected our way of life and the freedom that we all enjoy, including the right to protest, even protest dumb things.
