I understand your point about "not being a professional veteran" but I found the tone of your note a bit uncomfortable.
For the men who saw intense and sustained combat over a long period of time, these experiences deeply emotionally wounded and scarred them. They all deal with it as they see best.
But there is not a single one of these men who did not pay the price: physically, emotionally and spiritually for what they went through. Their time of high stress and tension during combat shaped who they are and impacted the rest of their lives.
Just because some choose to remain silent about it, while others speak out, I am no comfortable with the somewhat sneering remark about "not being a professional veteran."
I grew up with a lot of WWII vets and had the chance to speak to literally dozens, each would open up when they were ready.
For what it is worth.
