SA1911 saidthe only truly open minded people i've ever met were in the military where you could say a wide variety of racist, anti religious, and generally bigoted remarks and no one cared.
I'm not sure what you mean by this. When I joined the US Army in 1969 I never heard racial remarks at all. Not sure why, but the Army was the most racially integrated organization I ever knew.
Maybe because it was official policy, and it was enforced, no opportunity to express alternate racist views. Racism wasn't permitted, and in what was essentially an authoritarian society violations could be officially punished. Trust me, people in authority DID care about racist remarks.
We also had a lot of Black Drill Sergeants. I shudder to think of the fate of any Private who uttered a racial slur. The First Amendment protecting free speech is greatly restricted while serving in the US military, but there is no limit to the number of push-ups you might find yourself doing.
Furthermore as soldiers we all pretty much looked alike in our uniforms. Little opportunity to express ourselves in terms of our ethnic background, regionalism, our socio-economic standing, or anything personal about ourselves. There were times I actually did forget what the skin color of other soldiers whom I knew was, because such a distinction had no application or value in what we were doing. So I criticize this author's third point.
At the risk of making a cliched "some of my best friends" statement, my best friend for a year at one of my assignments in 1970-71 was Black. We were inseparable off duty, not an easy accomplishment in Kentucky in that era, when restrooms and water fountains were still segregated, and Whites stared at us like we were outer space aliens. But none of my fellow White soldiers ever criticized me for it, nor even mentioned it, just taking it for granted.
So I'm puzzled by your statement. If there are inappropriate racial remarks in the US military today then that is a great step backwards from what I encountered over 40 years ago. Before speculating as to cause, such as draft force versus volunteer, I'd like to hear others who've recently served comment on this.
