I wouldn’t draw the line where he drew it. He lumps all the civilians together. I would split between the bicoastal Metro cocoon (all anti-military) and the rest of the country (civilians and military).
Where I live and work now most people have similar values and outlooks, whether they were ever in the military or not. Back in the People’s Republic of California, I had little in common with the vast majority there, except the current military and veterans, even though I was a civilian.
