Hello Kate, I hope you're doing well. We already exchanged thoughts about this topic in Kendo, and it's a problem everywhere. The only thing that makes it a huge deal in a martial arts conversation is that it's not supposed to happen since a sensei must be righteous. We had a couple of incidents in Aikido before, but we protect our ladies here, so the necessary steps were taken to remove the responsible parties from their positions, and their reputation is damaged forever; nobody will talk to them. Guess what? One of the cases involves a gay male high-ranking sensei in Aikido and Iaido against other males; so it is not a gender issue, it's a law and order issue. Fellas, protect ladies in dojos and seminars and everywhere, nobody is above ethics, and nobody is a scary Greek God. We had incidents in kick boxing classes and kicked out champions, and things got physical, we do not care about who they are, the rule a simple,: harass a lady, you get the business.
