Ignoring this body of work makes the linked article a straw man argument with some cherry picked examples that don’t even make a point (why am I supposed to care that AOC tweets about some people at the exclusion of others?)
If your point is that not all leftists are intersectionalists and not all people who use intersectionalist words actually have the values, then I'd respond with, "duh".
Intersectionality isn't about telling one person's story or exemplifying one person's pain. It's about showing that these things are interconnected and effect people differently, and ways in which you probably wouldn't expect. It does the absolute opposite of a hierarchy.
(I could care less about AOC. She was like 1% of content of the article I posted.)

So to answer my question, no you can't provide a source.
(Also identity politics and intersectionality aren't the same thing, despite the right's habit of using them as meaningless scare words)
