I mean, you just answered your own question. The far left, and I don't mean just the "American-brand" of it, is very much focused on removing the categorization of individual identity - dismantling the concepts of race, sex, background, belief, nationality, etc. By removing those categories, the aim is to resolve the discrimination inherent in systems that inevitably have some bias towards individuals based on those characteristics, and ultimately make it infeasible to establish a hierarchy of any kind. Paradoxically, in order to do so, the far left must lean heavily into categorization to "remedy" the remnants of injustice that have been levied on groups of people and level the playing field.
