I remember a while ago at the dojo a new student asked one of our instructors after class what one should do if you were fighting someone who practiced <insert another martial art here> and they did <insert attack here>. It was interesting because everyone who had been practicing aikido for a while just basically turned away, rolling their eyes and smirking, while all the newbies turned and waited for the answer. The instructor just looked right at the student and responded "is that why you started aikido, to learn how to fight?" I think that student lasted another month or so, and moved on to the next martial art de jour.
If your teacher mocks you and fellow students laugh at you when you ask an honest question, I think that's a great reason to move on "to the next martial art de jour"; teacher sucks, students suck, it's a waste of your time and money. I'm sure they'll keep on twirling around just fine without you.
