Well I didn't read the entire website, but from what I saw, the quote I cited above seemed representative of the general attitude, so I'm wondering where the outrage is coming from. As a matter of fact they seem to go to a lot of trouble to make it clear that they aren't attacking the field of math or math pedagogy, but merely are trying to add resources that could help the teaching of math. Of course it's possible I missed something, hence the inquiry. But thanks for your observation.
