Good point. Why would this guy's service make any difference? Unless he was wearing a uniform how would anyone know? Years ago the left used to spit on returning Vietnam Vets. It seems that today's left doesn't give a damn except to use Vets as a propaganda tool.
Actually that is a myth. The only media record of vets being spit on is at the Miami Republican Convention, when William Buckley's Young American For Freedom cult spit on war protestors, many of whom were veterans. Vets were leading the march, in fact. They re-nominated Nixon. Many claimed that, usually citing the airport in San Francisco, which is of course immediately spotted as a lie, as the part of the airport where flights from VN were isolated form the rest of the airport.
Vets lie a lot, too. Nothing magical about being a veteran when it comes to self-serving bullshit. I come from a family full of them, grew up on Army bases.
