Re: What would you do? (Older male teacher with young female student)
I see 2 different issues here.
1. You blaming your leaving Aikido on someone elses behavior.
2. A dojo feeling unsafe because of a predatory older male.
My thoughts on # 1: I would not feel comfortable practicing in that dojo. I would find another.
My thoughts on # 2: I would tell the leader of the first dojo why I was leaving.
