Though I think identity politics has achieved many good and even some great things, compared to the alternative of making structural systemic changes I think it is a failure. And this I don’t believe is a false dichotomy, either.
Of course the Right does not support identity politics, not per se, but far prefers it to the alternative, which in a short time would eliminate them nearly completely as a social movement and diminish them greatly as a political one.
Which is to say that in the cabals and cliques of the Right Wing, identity politics and the adherents thereof are seen as a benign and tractable opponent, whereas mass movements like union organization and a more-effective Occupy are viewed as extremely dangerous and to be avoided at all costs.
So by “allowing” and lightly parrying and sometimes even encouraging identity politics, the Right avoids what it sees as a greater evil – that of mass revolts, true labor organization and their (in that scenario) unavoidable political defeat.
Identity politics serves – not by design, but inherent in the nature of its discourse – to divide what should be naturally-aligned groups, just as slave-owners and aristocratic whites during the Jim Crow era managed to align socially and economically poor whites with rich whites rather than poor whites with poor blacks, who by rights and lack thereof should have been natural allies.
I don’t begrudge the actual achievements of identity politics. But I do think it’s time to build on those and then to integrate coalitions. This creation of a true mass movement is more likely by far to change the world as compared to the current practice of estranging and alienating all but a tiny coterie with call-out culture and the busy and overbearing policing of other’s identities which serve only to prove your own credibility and authenticity.
