What we have here, essentially, are various (Leftist/ “progressive”) movements and individuals trying to discover – or invent – yet more minorities to exploit for their own political/social ends.
“The main thing 'intersectionality' is trying to do... is to point out that feminism which is overly white, middle class, cis-gendered and able-bodied represents just one type of view - and doesn't reflect on the experiences of all the multi-layered facets in life that women of all backgrounds face.”
“has created the conditions for the demise of 'essentialist' politics and the proliferation of new multiple political subjectivities. So, again, to make myself clear.... [capitalism] creates the very background against which 'generalised hegemony' can thrive.”
Multiple political “subjectivities” are a problem for Žižek. He wants the working class as a whole to fight capitalism. Or, at the very least, Žižek wants all the other subjectivities to unite behind the “hegemony” that is the working class (if led by a middle-class university-based vanguard). This multiplicity of subjectivities and “hybrid identities” simply muddies the water that is the ancient (Marxist) class war.
You see, what the intersectional theorists, postmodernists, poststructuralists, etc. don't realise is that all this
“playing with multiple, shifting personas... [simply] tends to obfuscate... the constraints of social space in which our experience is trapped”.
Indeed I'll let the reader indulge in the possible juxtapositions or permutations of the following “oppressed groups”: the “transgendered”, black, gay, women, black gay, white working class, black working class, rich ideologically powerful academics, etc.
