Again, I don't think it is an aikido thing or a ufc thing. It is about having good parents and common sense. It is easy to avoid fights. If you need aikido to help you avoid fights, you might need a psychologist not a martial art.
My work would throw up a dozen scenarios a week where it's not so 'easy' to avoid a fight. If that's been your experience, you have cause for much joy.
Incidentally, where I live Aikido is quite a bit cheaper than a psychologist!
