It may not be what you're talking about -- but doesn't that make sense of why someone might say "All politics are identity politics"? — Moliere
Because what happens is basically a confusion of process for product: identities (black, woman, gay, American) are results, products of an articulation arrived at in the course of complex social, historical, and cultural negotiation and development. One of the (necessary) means by which this negotiation takes place is politics, making it one (inescapable) ingredient that goes into the final, baked cake that is identity. Now, politics does alot more than just bake identity-cakes (not all politics, not
most politics, aims merely to shape identities), but
that it does, is inescapable. In is in
this sense that one might say that 'all politics is identity politics': if you engage in politics (or if politics engages you), you end up, whether you like it or not, articulating the contours of identity (among other things).
But this is very different from taking identity as the explicit site of political action, of taking
identification itself as a kind of political process: "I am woman, therefore, vote for me"'; "We put rainbow flags on our advertisements, so buy our products". This obscures process for product: this is what it means to engage in 'identity politics', where identities themselves are taken for (stand-in for) the very process which produce them. There's a interview with Deleuze where he talks about the difference between what he calls 'majorities' and 'minorities', which, for our purposes can be understood as those with established identities ('majorities'), and those who remain in the process of articulating theirs ('minorities'):
"The difference between minorities and majorities isn’t their size. A minority may be bigger than a majority. What defines the majority is a model [read: identity -SX] you have to conform to: the average European adult male city-dweller, for example … A minority, on the other hand, has no model [Identity - SX], it’s a becoming, a process. ... When a minority creates models [Identities] for itself, it’s because it wants to become a majority, and probably has to, to survive or prosper (to have a state, be recognized, establish its rights, for example). But its power comes from what it’s managed to create, which to some extent goes into the model,
but doesn’t depend on it. A people is always a creative minority, and remains one even when it acquires a majority [an identity]. It can be both at once because the two things aren’t lived out on the same plane." (
source, my bolding)
This confusion of process for product is what confuses so many people about identity politics, which is in many cases just assumed to be 'any kind of politics which has any bearing at all on identity'. Which is completely stupid because it's a confusion that ends up just equating identity politics with politics
tout court, and then you end up in the disastrous situation where politics itself is taken for 'the problem' (because 'everyone knows' identity politics = bad boogeyman). This is why anyone who thinks this is just merely a verbal dispute is pretty dumb, insofar as the stakes for thinking politically - for understanding what it is we are even talking about when we talk about and of politics - are pretty high.
