> Having a conversation that reveals to kids that their actions were unintentionally ...
Well I think "unintentionally" is a bit of a strong term, kids are inexperienced but not necessarily stupid, they understand power dynamics quite early. Humans have great intuition for that sort of thing.
> causing a lot of harm to their companions and then asking the kids what alternative kinds of rules they could adopt that would leave everyone feeling satisfied is “promoting hate”?
Yeah. We've got some examples of how this thinking plays out in practice - the people who want to mobilise a group to come down on individuals for social improprieties/organise public shamings are usually highly intolerant and, frankly, often seem to be motivated by hate. These are the instincts that power mob actions for generations. It is pretty routine, I'm not going to claim its in any way uncommon. I'm not even going to claim these legophobes are doing it, I haven't read today's article :].
But if you want to know why people would be nervous about teachers getting a group together to talk about individual's "transgressions" then this is the argument for why it is bad. It is inculcating a political opinion for how to handle social tension that is arguably bad.
> Which society are you thinking of? This is certainly not a fair description of the USA at any point in its history or of “Legotown”.
The US has a great track record. There aren't many countries where minorities do as well as the US. China is basically an ethnostate, India I'm not sure about, then suddenly in at #3 population we've got diversity central in the USA and the airwaves are chock-full of people arguing about how to make life better for minorities. Very attractive migration destination too (USA #1 and all that). Not exactly the sort of ranking that an intolerant country can manage.
