Personally, I think that while that might have been the internal justification for training in Okinawa, in practical reality, I don't know how much it was really used, against ruffians or anyone else.
I think more and more martial arts are going in this direction, no contact, practicality not a factor for training. I think most of my generation (and yours) took up the martial arts for "self defense" or like I like to say for "self offense" purposes, but today's generation is different, just like how you are different from your parents.
Not us in Hapkido we are headed the other direction.
