Hopefully I would not encounter such things but I feel that I have lost touch with reality given that our art is a "non-aggressive" one.
Do you have a question?
To ask a question of you, if you believe that aikido doesn't represent "reality", why do you want anything to do with it?
Reality is direct experience. It is what's actually happening to you now. It isn't fantasies about hypothetical encounters with stereotypical attackers.
