I'd feel better if you were a bit less condescending about the whole thing.
I spent 30-40 hours a week for three years outside my regular classload with ROTC duties. That didn't include the summer events -- Basic Camp, Advanced Camp, and Airborne school. I also had five hours of required classroom time every week - just like every other ROTC cadet in the country.
I'm not - repeat not - trying to pick a fight, but what you say is simply not true.
My jokes about ROTC programs are based in personal experience, and I realize that it is probably the minority, but it is not an insignificant minority.
I've sat and listened as politely as I could as groups of ROTC grads bragged about how easy their program was, about how meetings and classes often consisted of a simple sign-in, about how long they could grow their hair, etc. etc. etc.
I'm not saying every program is like that, but way too many are...
Give me back the time I've spent (wasted) teaching recently commissioned ROTC grads to wear their uniforms, how to enter a ship properly, how to give basic commands on the bridge, how to write a proper log entry, how to identify visual navigation aids, and on and on and on, and I will find a way to correct my attitude. (Yes, another jab, but one said with a smile...)
