Schoolkids don't generally do principled, public resistance like that unless they're specifically coached into it. They're still too young to be secure enough in their own moral framework to want to start a fight in front of all thier peers against some wolf-in-sheeps-clothing bullshit pretending to be "social justice", especially when even if they think they won't get shit from the other kids, they still know the staff will punish them.

I think a more typical response would be they just phone in a mumbled compliance and talk shit about the teachers pushing it afterwards with their friends.
