Teachers can't be neutral in the classroom about politics when one political party has declared war on the idea of truth.

The Missouri bill cited in the article is interesting, because it juxtaposes a valid point with an invalid point, in such a way as to partly hide the latter.

It is wrong to teach that certain groups of people are inherently or immutably racist, or inherently or immutably hold any views whatsoever, because such is prejudice. People vary, and people can learn.

However, teaching that certain groups of people are systemically oppressed, or that certain institutions are systemically racist, is legitimate because that is a verifiable fact about existing systems. Here's one example of verification.

This truth doesn't conflict with the truth that people vary and that people can learn. Systems can change, too, but that doesn't deny that they are now what they are now.

The bill groups people with institutions, and groups "inherently" with "systemically", so as to confuse.
