They use teaching resources like the "Genderbread Person", which pushes the harmful and oppressive social construct of gender in a child-like way, describing women and men in terms of sexist stereotypes rather than sex.

Both of these social constructs must be challenged. The first is used to oppress women and girls primarily, and the second underpins racist oppression.

Of course, I agree. But in the context of education if you reject the above (which MANY people on HN do) then you're delusional. There is nothing nice I have to say about it, and I know how dearly the HN crowd loves to clutch their pearls about the tone. It is akin to believing the world is flat, a broken ideology that should not be entertained.

Once you accept the simple facts as above, then you can finally explore the consequences.
