You could try to talk to the instructor, and let him know that his manner is not helpful for your training. If that doesn't work, you could try to go up the chain of command, and let the local organization leader know.
Otherwise, your only options are:
* Deal with it
* Find a new school
Personally, the instructor sounds like a jackass to me. Good luck.
