You don't like an instructor so you want to bail. You probably won't like a MIG on your tail either but pulling the loud handles isn't going to solve the problem. Sounds to me like this person is out to see what your made of. And I might add with good cause. Your entering a field where only the strong survive. If you can't take what this boy is dishing out he very probably saved your life. If you decide to light the pipes and turn and fight, he very probably saved your life. He knows where you're heading and he wants to be sure you can give as good as you get.
