I voted yes. When I teach, I don't implement much ceremony. I do tell my students what I know about what spiritual and religious things O'sensei did in his dojo, but I don't do the same things.
Aikido helped to turn me into a person that was worth marrying. Aikido has helped a friend of mine to calm down after years of military and "hard style" training. Aikido has brought me into contact with people that I might have never known, and cultivated our friendship.
Yeah, I think that describes my experiences pretty well.
