I don't see how a man can write this nonsense. How ridiculous. "PTSD"? Come on.
The Authors name is "KUNTZMAN", that explains a lot! He caught a ton of crap for that article and he posted some of it in his follow up (at link). Pro gun control, democrat, Clinton supporter.

From the author: UPDATE: Many people have objected to my use of the term "PTSD" in the above story. The use of this term was in no way meant to conflate my very temporary anxiety with the very real condition experienced by many of our brave men and women in uniform. I regret the inarticulate use of the term to describe my in-the-moment impression of the gun's firepower, and apologize for it. I have also posted a follow up piece here.
