I think the point they're trying to make is that anti-intellectualism means distrust of all intellectual pursuits and those who pursue them, not some specific ones. For example, let's say there is a group that believes that only those that study rock music are truly intellectual, and holds them in high esteem, while thinking that all others (including physicists, great writers, prophets etc) are lesser minds and not worth paying attention to. This group is not anti-intellectual, as they hold intellectuals in high regard, though having a wildly off-kilter definition of one. In contrast, many groups view study itself as a bad activity, and those that practice it as haughty, distant, idealistic, and generally not worth listening to - these groups are what it means to be anti-intellectual; the kind that praise "street smarts" far above "book learning". People advocating for math education as the most important form of human thought are nothing alike (though I do agree they are also wrong, in different ways).
