I don't know who the pope of modern intersectionality is, so I don't know what It dictates. But your formulation, if applied to abolitionists, would read like "Abolitionists dictate that people should be treated very differently based on whether they are currently enslaved"
But are you?
I am sorry, but this is one of the most useless definitions I've read lately. Almost any human activity and any point of view can be described as "about how one describes reality", from quantum gravity theory to buddhism. And, on top of that, it does not contradict the premise bitlax described above.
I am all for thinking critically but if you proclaim that the description above is wrong - and not only just wrong, but so obviously wrong as the wrongness to be obvious to the author, and thus "bad faith" - I think the minimum requirement for you would be to produce a better definition. And "read the wikipedia, it's all there" is not providing a better one.
