If I had a dollar for every time my wife (three degrees, and two professional certificates) came home from some department store, after having been jerked around by some twit, and said: do you know what I should have said to her?" I would be immensely wealthy.
The reason the female gender gets jerked around more than the male, usually by other females, is that they put up with it.
The two best teachers I ever had NEVER raised their voice during a lesson. They were always analytical in their approach and constructive in their criticism.
Finally, I have had my fill of this garbage of thinking that studying under some Russian abusive witch is a legitimate way to teach piano, much less anything else. It is straight up and down abuse, and should never be tolerated.
Under any other circumstance would you ever pay people money to yell at you? Of course, you wouldn't, and you should not be doing it here.
Move on, and if you can, find someone with a Taubman/Golandsky background in technique. Their professionalism will astound you.
