You ever play sports? Or watch the coaches on the sidelines of a football game?
That doesn't work when peer pressure is necessary, and immediate correction of behavior is necessary.
Dude - I spent 32 years in the military working for special and joint ops of all kinds and working with all branches. I loathe the military that folks such as yourself have turned my military into. And YES - I ended that sentence with a preposition. It's the sort of low-brow thinking that gets things done.
I watched this transition of our beloved services - from when I enlisted under Reagan in 1987 - until I retired just last year in November of 2018. There were GOOD things that happened, things such as women not being harassed needlessly. But there were idiotic things that happened too - such as the creation of the snowflake military where a man could lose a career because he's trying to put some toughness into a weak man that he knows won't survive the first sound of gunfire in a combat situation...and sometimes a little public humiliation is the best way to knock an attitude out of a person.
ESPECIALLY these entitled Saudi pilots - who I spent time with over at PSAB and at other places - a bunch of entitled pricks (extensions of the royal family mostly) who think their you know what doesn't stink. The jumped in their F-15s and flew on afterburner over the desert for 10 minutes straight and RTB. That's all they did. Flew fast and acted like a bunch of rich spoiled brats.
And that is probably EXACTLY what this guy was acting like in class. So if a little public humiliation was due - then so be it. And if you don't understand that an instructor shouldn't be given that latitude and you don't understand that the POLITICS we live in wouldn't give that instructor the option to throw that snarky prick out of the course - I can't help you. He was probably left with no other alternative than to check his attitude with a little verbal slap every once in a while.
You sound like an Obama general.
