Re: High level power abuse
Something that I would certainly be asking myself as a female student: is this a singular event or is it part of a pattern? If it is a singular event, I would probably confine myself to, at most, making it clear that I didn't want to be a witness to this and they should not bring it to the dojo. But if there is a recurring pattern of mixing dojo business and personal business I'd be a lot more concerned.
Is the teacher just and impartial in testing and training? Does he clearly separate how he feels about a student from how he feels about a student's aikido?
