First of all, it is not "high school ROTC", it is JROTC. There are some anti-ROTC stuff in college, but very little anti-JROTC in high school. You really notice the age difference there, so the whole world is not laughing at them.
JROTC helps getting a place in a good ROTC program, but very quickly after that becomes unimportant. I would not call saying you were in JROTC "stolen valor", and am unsure why you are so crazy about it.
No, I was in JROTC. There is no such thing as "high school ROTC." To be in ROTC, you must be 18 years old, and in college(not high school). That was almost 40 years ago, so has little bearing on my current life.
Why do you hate JROTC so much?
