I know the concept of intersectionality has been embedded into mainstream liberal feminism to a point where you’re not really allowed to question it any more, there are still many radfems to point out the problematic aspects of it, and ultimately why it helps further the exploitation of women. Here is an article from Aphrodite Kocieda published on Feminist Current on this topic.
First of all, the actual framework that intersectionality operates from is problematic. I would argue that intersectionality operates from a white supremacist patriarchal foundation. Therefore, all populations excluded from the mainstream normative space, focus on how they’re excluded, not why the space is inherently exclusionary. Bitch magazine ran an article on intersectionality wherein the writer states: “’intersectionality’ becomes code for ‘wait your turn.’ Rather than being a reflection of a highly inclusive movement that integrates different lived experiences and priorities, it is used to say ‘just as soon as we get our needs taken care of, we’ll turn to yours.’” Through intersectionality, we are caught up in a discussion over who is “left out” of the current model because the actual model itself is exclusionary.
