On the off chance that anyone pro-idpol is reading this, please give it a chance and let me explain my reasoning before you put me in a box of being a 'brocialist'. I will admit not being as familiar with the work of intersectional theorists like Crenshaw as I should be.
These are my thoughts.
Here on anti-identitarian left, we dislike IDPOL. But the reasons for this are far more nuanced than are usually given credit for. The pro-idpol person reading this probably imagines that the anti idpol leftist is some white macho dudebro who is a barely reformed fashie that likes the economic parts of socialism only because they affect him personally, and doesn't have enough empathy or is ignorant of the struggles of other groups. And to be sure, there actually are some people that match that description and use 'anti idpol' as cover to be a douche. That is wrong. Racial discrimination is wrong. Homophobia is wrong. Bigotry in general is wrong. We all agree to this at least in principle on the left.
But that doesn't excuse problems with identity politics on the left.
1. Corporate Co-opting. When we see Colin Capernick getting nike endorsements, feminism being viewed positively by mainstream media outlets, etc. We can see that wokeness and corporate capitalism are not incompatible. that is not to say that feminism etc. are bad, but just that they do not challenge the system in as deep of a way. Indeed, if you look at many pride parades today its difficult to even tell that acceptance of and visibility for LGBT+ is the goal of the parade, or rather the glorification of the tech industry, as you see the marchers holding up signs that say INTEL, MICROSOFT, APPLE. You can have (and often do) major corporations endorse feminism and lgbt+ issues wheras amazon would obviously never endorse a march to increase the minimum wage or pro-union. This is the sort of "woke neoliberalism" epitomized by people such as Hillary Clinton and the tumblr crowd - The Californian ideology. Sex, Drugs, and fiscal conservatism.
