He showed me the video and we talked about its content...I guess he posted what I said here...no big deal.

As to your question, I have one basic rule concerning behavior. You may pay attention or not, your choice....but in no way will you distract from the other students that choose to learn. Disrupt my class and you are shown the door. Like he said, my school has the support of the teachers in the majority of disciplinary matters. That hasn't always been the case here, and my job was definitely much more difficult then. Having an administration that is willing to take the heat from parents instead of caving in to them makes a world of difference.
