Further to the thread topic than trying to explain it to catamount tonight, banning the teaching of a concept is silly. I remember being challenged by a few ideas I came across to the point of both intellectual discomfort and disagreement, things like epistemic privilege or the idea that assimilation a la “the melting pot” is perhaps antithetical to a pluralist, or at least multicultural society.
But much like other concepts I disliked or disagreed with in philosophy (utilitarianism, the categorical imperative) or in economics or political theory, it’s one thing to read and discuss an idea and another to just accept it as part of your worldview. It’s downright cowardly to ban the teaching of a concept, ideas in academics should be debated and discussed on the merits of their arguments.
If parents are worried their kids will get indoctrinated, they should do the work at home to challenge the thinking of the pedagogy and force their kids to think critically and engage them the same way a teacher would. I can’t imagine being scared of my kid encountering an idea that’s so dangerous that I’d never let him hear it.
