Around the time of my shodan test my home dojo was joined by a returning aikidoist, a middle aged gentleman some decades years out of training, from a certain very proud lineage different. This is killing me; I love the art, but the culture that accepts and enables this repels me. What would you do?
Hard and fast reality check, no beating arond the bush. What is with the comprise mom? Any good parent would not question what to do. You sound like a good parent. How can a parent even make a choice between their child's welfare and a recreational activity. A 40 YEAR OLD MAN has no business with teenagers. This is an emotional and personal issue for me too. As a father who does aikido I would not hesitate to leave that dojo instantly.
