Well, you did break a rule and got punished for it, so no, in the beginning you weren't in the right.
However, to be fair, if what you said about the teacher behaving that way to you is true, then he's being a power crazed asshole, just looking for an excuse to jump on someone. I had teachers like that who I would regularly fuck with because they would fuck with me.
I wasn't a very popular student.
Regardless, grabbing you by the collar and such is wrong yet what you did broke the rules, so yes, you are in the wrong but they only made it worse by punishing you in that way.
And I would have and have done the same thing, so I'm not one to tell you what you did was wrong and that you shouldn't do it again. >.>
