What is even the end goal of Intersectionality?
Like, sure, you've established the proper oppression arithmetic and you now know a person with those and those traits is lower in the hierarchy than a person with those other set of traits. Where do you even go from here?
If this is going to translate into anything material other than mere in-fighting, you must go to politics. With politics, you'll still have to settle with the following: what can be done to help those oppressed people is still largely defined by the machineries of the state. This, in turn, is defined by questions of political economy, of public initiative, of welfare, of taxes, all of which Intersectional theory does not prepare you to deal with at all.
Then you have the question of the origin and character of these "systems of oppression". Black people have it worse in America, why? "Because white people are racist" would be mistaking cause and effect. Bigotry between different groups in different positions of power will always exist, no matter how many words or habits you try to censor or legislate. The cause is material. It's about historical poverty, social stratification, about how unequal access to proper education and training is, the difficulty of social mobility, and how these are perpetuated by a system that is defined mostly by inheritance and private property, and all of those have to do with questions of history and economics.
Someone with a materialist, economic view of history would look at the latter to find answers to the former. You identify the material roots of oppression and you expand the means of democratic public initiative accordingly to provide a solution. Intersectionality does not necessarily negate that, but usually it's stuck inbetween, concerning itself more with who is more oppressed and why, accepting prevailing political dogma to provide a solution (hence yasss queen Hillary womyn in the white house) and mistaking individual bigotry of those "above" as the source of oppression. Which is why now they're trying to exorcise racism even when there's none, going more and more into "subconscious" and "internalized" white supremacy, because their entire analysis depends on that. Once you get rid of those, they'll come up with new signs of internalized white supremacy and new norms for it, and black people will not be a single step further in fixing the gap that exists between blacks and whites in America.
So it's easier to just reject and instead focus on the material, on increasing the democratic control over ou material ways of life, which will provide any group with a wider array of choices and mechanisms to engage inequality. Then, hopefully, this is where their energies would be focused, instead of complaining that white people are appropriating their Vine memes.
yeah I know but for the most part they're not Marxists not even socialists, just liberal shitdicks
