Can you watch this video, then read this response I found to it, and tell me what you think?

Here’s the video. It’s a veteran giving his opinions about war. My friend on facebook posted this, then I read this from another person I know:

“This is a pack of lies. This is the sort of seditionist propaganda that destroys the unity and patriotism of this nation. And will only bring our downfall. Which is what our enemies want. This traitor is assisting those who would destroy the civil liberties that we all take for granted.”

This response struck a chord with me because of course one would expect this type of response to such a genuine response from someone who has lived this lifestyle. I want to reply to him so bad, but I think I should just take the high road. What do you think?
