Not sure if this one of those you already read, but anyway, it sets out her views quite well and explains several of the quotes in the article, as well as the 'conocimiento' thing.
There's a few parts that I'm sceptical about. Saying mathematics has 'unearned privilege' because mathematical aptitude or insight is taken as a proxy of intelligence more than aptitude in other subjects, is reasonable enough - but she seems to be cutting a lot of corners in the casual dismissal of mathematics' claim to deal with objective truth.
But the most important thing that I'm taking away from the article is that in the end her goal is the same as that of the people criticizing her in this thread - helping students to fulfill their potential in terms of learning mathematics as well as possible. The interpretations of her quotes as if she's aiming to reduce or weaken mathematical teaching are very wrong.
