@mloxton I'll play it straight [Edit to delete a bit: apologies, I shouldn't post when I'm still waking up, I misread the thread of conversation and lost track of who's who. I agree malicious compliance is one good course of action but I also think resigning is a good course of action, it's up to the person - the main thing is to resist in *some* way.]
Yes, the kids are better off for seeing a concrete example of their own teacher standing up on a matter of principle instead of caving to authority.
Some other teacher will come along to teach them whatever the curriculum is. But this memory of their teacher considering freedom of speech and inclusion of everyone to be so important that it's worth saying "no" to authority over and resigning - that will stick with them forever, and that will make them better people.
