As I wrote to one Mr. Ponytail, violence was inevitable. He had nothing but alibis -- removing the student in question would require hearings, etc. I said, so let's have hearings. Eventually, I had to go over his head to the school president, who saw to it that the thuggish young woman (who had male friends and relatives come to the class to harass me, in addition to her own constant disruptions) stopped showing up. Then at the final examination, she reappeared, claiming that the black, female student counselor who was tight with Mr. Ponytail, had told her she could take the exam. Considering what a racist the counselor was (and malingerer! The only time she exerted herself, was in encouraging the most thugggish students in school to keep up their shenanigans), it wouldn't surprise me, if she had told the thug to show up, just to provoke an incident.
Although a Cuban security guard had told me to let him know if she showed up again, I let it pass. I believe she got a zero on the test, and even if she'd passed, I'd have flunked her for gross misconduct. (But since she was also academically the worst student in class, there was little chance of her passing anything.) and yet, it wouldn't surprise me one but, if my boss overrode my "F," and passed the thug. After all, she was welcome there; I wasn't.
A new, white instructor confided in me that an assassin had showed up in his class one day, looked over the class, and left. (He didn't say "assassin," but that was clearly the upshot of the story.) The guy was too embarrrassed to tell our boss, Mr. Ponytail. He had already figured out, that Mr. P would sympathize with the assassin.
I have no doubt that Mr. Ponytail was using black and Hispanic students, to wage war on white male instructors.
