I think theres a MASSIVE difference between ridiculing the lunacy of the ideology and bullying individual kids. The problem is the individual kids will take it personally because they are vulnerable.
But ultimately the ideology is crazy. Especially the non-binary stuff. You can't just pretend it isn't because that has ramifications. Being nice about it, doesn't work because ultimately its harming kids - not just mentally but also physically. You can't just 'remain neutral' and passive as a result, as the say nothing/do nothing position isn't neutral.
Having kids willing to stand up to 1984 levels of shite IS to be congratulated. Not because its against kids, but its against abuses of power. The whole "BeKind" thing with no critical thinking IS an abuse of power. It is coercive. It uses emotion to manipulate your behaviour and do / say things you feel uncomfortable with and don't believe.
The fact that kids are questioning what they are being taught to think, and are in effect, starting to rebel against that is good. And also interesting. Culturally British kids of a certain age (coincidentally this pre / early teen period) have tended to kick back against authoritarianism and thats probably also an element to whats starting to happen as liberal inclusivity has stepped over into authoritarianism imposed from above. The shoving of the rainbow so forcefully when the kids can see the problems with it, WILL lead to a backlash. The idea that a backlash would only occur in older people is silly, when you think about how you were as teens. Its the tedium and repeatitive stuff that leads to the ultimate switch off.
And of course, given the disappearance of an entire 'school tribe' from modern uk schools, the question of where they went is an interesting one. The school tribes are known to occur in almost every western culture in the world regardless of language. Its part of the hierachy in schools so the idea it could suddenly just 'disappear' is strange. We know there is a clear link between the Punk, Goth, Grunge, Emo tribes that all were in the same type of person, just at a different time. Social contagion is really hard to ignore because of the pattern. And Anime with the online technological change / culture shift was the natural successor. They were always the 'outsider'. The other kids generally tolerated them, and DIDN'T bully them (though a minority definitely did) but the other kids thought they were weird / attention seeking. Nothing has changed on that score, apart from the fact it was off limits to express this due to 'The Fear' of the 'BeKind' witchhunters. And 'The Fear' in itself is not nice and carries more than a tone of bullying and intimidation itself. Its hardly inclusive of diversity of thought.
(As an aside, I find it fascinating that the latest Pokemon games are showing a shift and theres a big change planned. Some history: For the last 30 years Ash has been the hero of the cartoon and you could only play the games as a boy. News has recently come out saying that Nintendo is planning to axe him and replace him with a lead for the first time. The latest games - Scarlet and Violet allow you to play as a girl for the very first time. And the new series, inside of having the bad guys 'Team Rocket' there's a new group of baddies. And heres the interesting bit - the premise is they are the kids who were bullied, who ganged together and hit back and in doing so pretty much became the bullies themselves cos the school had failed to deal with the problems properly. These were good kids who were well intentioned but ended up taking a wrong turn and needed the school to realise the problem and bring them back into the fold and not fail them. 'Team Star' as they are called all dress up in strange clothes compared to all the other characters almost in the style of punk, emo, goth, anime lover - unlike the rest of the characters in the game. I can't help but think the timing is most intriging given real world narratives and whether there is this sense that 'the blue haired animes' have almost taken the outsider culture online and in how thats leaked to the real world to its limits and there's starting to almost be a recognition of this narrative forming around the world)
Where the UK is different is how the school tribes are slightly different to the US tribes. We have the 'cool kids' and the 'sporty kid' tribes but they are less extreme than for example the cheerleader girls and the jocks. I forget the full list (it was something like cool, sporty, nerds, goths, chavs/neds - I'm sure someone can enlighten me). So it possibly isn't a surprise that theres change / kick back here sooner especially as parents are less on board and we don't have the whole democrat/liberal v republican/religious nutter thing going on here too.
The phrase that sums up this conflict which perhaps looks contradictory to say that 'yes you should be supportive of eye rolling' at non-binary/trans craze is this one: “We must all face the choice between what is right and what is easy." It is certainly not an endorsement of bullying these kids.
I think many of teenagers eye rolling and calling it attention seeking can very clear see the kids doing it are troubled in some way, and perhaps need help (help which a teenager is rarely able to provide - precisely because they are kids themselves too). I think the point someone raised upthread about the other kids 'steering well clear' is grounded in a recognition of this and avoiding getting sucked into the drama / trouble in the NB / Trans kids lives. Cos most kids, whilst not necessarily supportive of the nonsense also aren't going to be horrid and engage in deliberate bullying either. The limit is probably sighing, eye rolling and piss taking out of exasperation at the demands being made of them. Which I think most adults would do. The line is where exasperation crosses to targetted vindicative attacks rather than just being thoroughly fed up of it.
Reducing the things going on here and the relief others on the thread have about kids maybe realising theres an issue to 'supporting bullies and hating on people' is more of the same divisive narrow drivel that got everyone into this mess in the first place.
