Re: What would you do? (Older male teacher with young female student)
If you are not comfortable at a dojo, you shouldn't train there and shouldn't encourage your daughter to do so. That's independent of the objective reality of the situation. Only you can decide whether you are comfortable allowing your daughter to be around these people.
But there are lots of other dojos. It's one thing to say "this dojo is wrong for me," quite another to abandon the art altogether.
