I upvoted you. It's a good story and far more common than most people would like to believe. But I would caution you against generalizing your anecdotal evidence to the profession of teaching as a whole. Some teachers would do exactly what you did and throw the bully's out and the vast majority wouldn't blame the victim. In my relatively large (but admittedly still anecdotal) experience with CPS and public suburban schools, I've only seen teachers close to what you describe in a small fraction.
