Because you're an aikido black belt??
lol. Well this is probably why I am so experienced in this topic of dissonance. After doing martial arts in the Traditional sense for 15 years, I had to face a bunch of soldiers who didn't really care what my background was and refused to recoginize my training "experience".
It was a disconcerting few weeks of trying to take inventory of what I had been doing for the last 15 years!
The good news was once I figured out what was going on, it allowed me to embrace a new way of training. I found that because of my background in aikido and TMA, I was able to advance fairly rapidily in gaining new skillz.
So the good news for most of us, is that our training does not have to looked at as a waste of time.
