I was young at that time, but remember my family sending care packages to Viet Nam to a son from down the street, and how happy we were when he came home. No I didn't agree with the vilification of those who served then or now. I hear you did go and had a tough time. I'm sorry for that, and that our country sent you there. I've watched, read and discussed military service with all kinds of Americans, and folks overseas-some service members and some not. I'm sorry if what I said felt disrespectful to those who served. Not my intention. I did want to express my right to protest war, and just speak my opinion as we are allowed here. I think if our nation spent way less effort in making war, folks like you wouldn't have to participate. 

As for the current protests-I think the vast majority are peaceable folks demonstrating their right to assemble as given, and before even needing defense. Sadly such demonstration always attract uninvited anarchists who infiltrate, burn and cause damage.
