There's almost no opponent of the blank slate theory who thinks societal factors never matter. There's only one side that takes a hard-line dogmatic view on this issue and it's the blank slatists.

Blank slatists?

Of course they do. Even if someone actually believed in some 'hard' type of ideology, they might not act that way.

It's just a 'general set of principles', intuitions, pop culture ideals that lead a large group of people to assumptive believe that 'unequal outcomes are driven mostly by systematic racism' and that's that.

Ergo 'the world is deeply racist' and 'there is racism around every corner' including in your math textbooks and teaching.

Ad nauseum.

Some of it is actually correct.

Some of it is reasonable from an intellectual perspective, but it's hard to take anything from it.

Much of it just ends up being toxic.
