Looking onto this, perhaps The Movement Apologist could be a new Type of its own, thus making it Type 11.Type 9. She's part of a relatively young species of the Type 9, the Movement Apologist.
The movement apologist is, traditionally, a leftist with considerable cultural guilt, typically imagined due to indoctrination by the ideology. These are the poor shitheads that can get baited into say, donating to black extremists for "reparations," or who get browbeaten into acting against self-interest. Others are fully aware of what they're doing, but are doing it anyway because MUH NARRATIVE, and they want to force their angle, truth and audience be damned. Sarsour falls into this subcategory, as her shit doesn't pass even the most basic of musters and led to a fucking amazing throw-down by an incredibly based Imam (Imam Tawhidi, who she will never fucking respond to):
Tawhidi is fucking awesome, as a side-note, wish we had a dozen more like him.
Movement Apologists act the way they do to for different reasons, depending on the subspecies: either footslog for the movement in spite of the fact that the movement hates them (see also: Men backing feminists who hate men, white people who back Gazi Kodzo, et al) because they feel obligated to due to percieved past misdeeds, or alternately because they feel that if they do not, they will be labelled part of the problem. The more sinister variants, like Sarsour, do it because they know they can get away with it for the moment and will attempt, over time, to gradually turn themselves into a Type 1, 2, or 4.
