Actually, there is no defense here.......the fact that you are not really bothered by this is telling in itself, and should be a red flag for you. Listen to your senior club members as to what is considered appropriate aikido/dojo behavior. Let them be your guide.
Yep. The late Gayle Fillman Sensei was known to remove people from membership short term or not allow them to rank if their dojo OR public community behavior was egregious. Having trained at other dojos where people got away with all kinds of nonsense I found this a refreshing stand on the role of ethics in budo.
