The truth is we have more in common with people of different ethnicities and religions than we can possibly know in a totalitarian system drenched in the divisive propaganda of identity politics.
Identity politics are the core of every totalitarian state. Identity politics were the beating heart of Nazism, and the core strategy of the USSR's liquidation of kulaks and other groups identified as enemies of the state.
Identity politics eliminate the potential for class consciousness that crosses ethnic and religious boundaries. As noted yesterday in Our Impoverished, Pathological Society, "race is not a significant determinant of social polarization in today's America. It is class that really matters."
Identity politics divide and fragment the debt-serf class into ethnic and religious silos that are propagandized into viewing each other as enemies rather than colleagues. The core of identity politics is if you fail to vote the party line, you are a traitor to your race/religion.
The appeal to ethnic/religious identity as the sole definition of political selfhood is the perfect tool for manipulating the masses--and this is why the only possible output of identity politics is totalitarianism.
In the U.S. both political parties deploy identity politics, but the Democrats in particular depend on the "if you don't vote the Democratic ticket, you're a traitor to your race" line of propaganda.
