In my experience most aikidoers I met are really nice and helpful people.
But then again, so are most people I met in the karate club, go glubs and people I met at work, parties, holidays, you name it
So perhaps is not so much an exception. Perhaps people in general are nice and helpful
Or perhaps you are nice and helpful.
I've definitely noticed that people attract reflections of themselves: helpful people attract helpful people, selfish grumps attract selfish grumps. And so their expectations of the world are shown to be justified.
