No I am saying that trivia is trivia. What happened is at worst micro-bullying.
Actually I suspect the daughter did not want to do the course, was pressured into it by her mother and pickup on on this minor incident as an excuse to stop the course.
It's not 'perverse' to have different standards on what qualifies as punishable bullying. You're using some kind of false equivalence here. Yes, both an insult and a beating qualify as 'bullying', but that does not mean we should categorize them similarly.
Given how common such bullying is, particularly in relation to such a male dominated field (and class), you are absolutely wrong. And having a group gang up on you is anything but "micro-bullying".
