I mostly agree with your post - I was not supporting violence via bullet points. My point was the inbalance of treatment of kids in the US school system. I.e. disciplinary actions are extreme in some cases while terribly lax in others.
I read several versions of the Female student expelled for kneeing boy in the groin story from varying media outlets attempting to read through the lines and be objective about each perspective. Reading the different versions of the story I came away with the impression that the boys were blocking the doorway preventing her from leaving the bathroom. In the US that is called false imprisonment and is loosely defined as: not requiring force or intimidation, confining or detaining another person against their will and without any legal justification.
The boys had every right to protest, I 100% support their right to do so and I agree they deserve dignity and privacy as well as the girls. The selfie taking in the boys bathroom by the trans student is bizarre an inappropriate behaviour. But, I do not support anyone in the false imprisonment of another (if they didn't great, if they did then they should receive guidance on how to peacefully protest without breaking standing laws - not be arrested or anything; they should be given the opportunity to learn about their rights in regards to protesting).
From what I've read no one detained or confined anyone on Man Friday (I don't know much about UK law and do not know if you have a similar law for false imprisonment) and from what I understand no one entered men's changing rooms only the bath (I am happy to be corrected if I'm wrong) whereas boys invading a girls bathroom allegedly detaining a girl is possibly false imprisonment by US law so I think it is a poor comparison. Also, you are comparing an adult protest in the UK (hopefully aware of protest rights) to a kid protest in the US (except for knowing they can protest they probably have no idea about the rules of peaceful legal protests).
Furthermore, the girl was expelled from school in North Pole, Alaska - they have a population of 2,101 and one high school with two campuses, so getting kicked out of school for kneeing a boy in the groin seems quite excessive (and possibly created a difficult path to high school completion for her). A week's worth of off-campus suspension seems more appropriate if it is found that she wasn't detained. If she was detained what kind of message does this tell her and other girls (and boys or trans) about feeling like they have a right to escape unlawful confinement by other students at school, they get expelled? Are they (kids) allowed to have any boundaries or to assert said boundaries? It seems that the Dept of Education is stripping all children of their ability to assert boundaries... adding more challenges to sexual assault report enforcement while opening single-sex spaces to everyone (in violation of current guidance on Title IX). This situation came about because boys were pissed (rightfully so) that a transboy was taking selfies in the bathroom, the trans kid should be reprimanded (as should any kid it's super inappropriate). Adults that take selfies in open-plan public restrooms are fucking morons regardless of their sex.
High School is a tough time for girls and boys; while as adults we may or may not feel threatened by a similar situation we may feel very different if we were back in our teenage skin.
