When I read about bathrooms, college chalk prohibition, and safe space, my mind drifts to precious memories of the military.
Expressing anger is a required leadership skill...believe it or not. As more diverse folks enter military service, I wonder if they understand they will be entering another world. The military industrial complex mission is to Win America's Wars; not to make folks safe and included. Your life and millions of dollars are expendable to meet that goal.
I received one special treatment when I forgot that I was a second class citizen (enlisted man) and forgot to salute a Marine Officer. He was wearing the black insignias that prevent snipers from selecting officers at great distance. I did not like saluting officers.
Back to the photo, this instructor is teaching the young man how to survive. Apparently, the AIR Rule (Attention, Interest, and "Repeation") needed repeating. Sargent most likely is a combat vet and has their best interest at heart. When the enemy is at the gate, who you gonna call?
Conclusion: The reason VN vets at Famous Joe Bar and Grill laugh at college students and intellectuals is obvious. The real world is a Cruel Space not a Safe Space.
