Obviously this is not a big deal but it does irk me sometimes when people include ableism alongside the other isms or when they say shit along the lines of "as a disabled queer POC". The logic being whatever aspect of your identity "disadvantages" you the harder you have it and the more righteous you are. It really is straight intersectional bullshit and trivializes the fact that race and gender are all things that are violently enforced to maintain the political rule of capitalism. It is true that disabled people suffer disproportionately under capitalism, especially under the pretext that all humans must work to produce value for profit, but hell capitalism fucks over all kinds of people. At the end of the day its just not a special form of oppression that deserves the same level of attention as forms of oppression literally centrally to capitalism. The reason questionable languages like this takes hold is because there is a plethora of liberal or straight up reactionary theoreticians the likes of Slavoj Zizek and Judith Butler that dominates the intellectual sphere and the revolutionary kernel of Marxism completely buried under paragraphs after paragraphs of indecipherable bullshit made up so some humanities professor can keep their pathetic job.
I think also the widespread use of intersectionality causes a negation of it in reaction whereas the Marxist-Leninist term coined by Claudia Jones "layered oppression" inherently relates how systems of oppression interact with more clarity.
