change is sometimes appallingly slow

Despite promises to reform their textbooks, the Saudi education system continues to indoctrinate children with hatred and incitement

You’ve got to be taught to hate and fear,
You’ve got to be taught from year to year,
It’s got to be drummed in your dear little ear.
You’ve got to be carefully taught!

You’ve got to be taught to be afraid
Of people whose eyes are oddly made,
And people whose skin is a different shade,
You’ve got to be carefully taught.

You’ve got to be taught before it’s too late,
Before you are 6 or 7 or 8,
To hate all the people your relatives hate,
You’ve got to be carefully taught!
You’ve got to be carefully taught!

(from the film South Pacific).
