As socialists we are often ridiculed for some sort of class reductionism and people often ask why should other identities be boiled down to their class character? I would like someone to elaborate their views upon this and list down some readings maybe that would be helpful in this context. Intersectional theory especially had made huge advances in academia recently at the cost of a materialist analysis of society. Maybe also list down critiques of intersectional theory especially the ones that give a lot of contextual details as in what historical formations and wider socio-economic processes did intersectional theory emerge?

PS: I have already read basic level criticisms of intersectional theory and would like something more profounder indepth sort of analysis instead of generalisations.
