Re: verbal abuse from a teacher
You don't state your gender, but I get the feeling that you are female. If that is the case, RUN, RUN, RUN! You are dealing with someone who is dangerous. If you are a male, WALK AWAY FAST. You are dealing with someone who is abusive and doesn't have your best interests at heart. There is a huge difference in the boot camp atmosphere of an Explorer Academy and a dojo's student-teacher relationship. At the academy every one of you was yelled at and found deficient, as opposed to being singled out by an authority figure.
I've heard my teacher raise his voice to a student once in the past eight years when the student, who should have known better, was doing something both prohibited and very dangerous. Sensei is an old-school teacher and doesn't put up with nonsense, but he doesn't belittle or demean anyone - and he certainly doesn't hide his actions.
