Columbia Teacher’s College responds to the critique from the Foundation for Individual Rights in Education I mentioned below, and they’re at least claiming the case is essentially what I’d suspected: The business about social justice and appreciating the effects of discrimination is about, in practice, being able to tailor your teaching style to respond to students shaped by different circumstances, not about parroting any particular political line. I suppose you could argue that these aren’t wholly separable, but I’m inclined to give the benefit of the doubt.
