An answer to the question: What do the Lefty billionaires, effete well off gays, ghetto blacks and their Latino rivals for turf and jobs, and straight white coed girls have in common?  Hatred of the common enemy, straight white men.  Only thru stoking adequate levels of racial and sex based hate can the Democrats remain unified

(from Vanity Fair "Why Democrats are Becoming the Party of the 1 Percent" by T.A. Frank )…. Democrats would become the party of globalist-minded elites, both economic and cultural, while Republicans would become the party of the working class....

The combination of super-rich Democrats and poor Democrats would exacerbate internal party tensions...That’s one reason why Democrats have devoted so much attention to issues such as transgender rights, sexual assault on campus, racial disparities in criminal justice, and immigration reform. The causes may be worthy—and they attract sincere advocates—but politically they’re also useful. They don’t bother rich people.

It’s a costly arrangement. The more that Democrats write off the white working class, which has been experiencing a drastic decline in living standards, the harder it is for them to call themselves a party of the little guy. The more that the rich can frame various business practices as blows to privilege or oppression—predatory lending as a way to expand minority home ownership, outsourcing as a way to uplift the world’s poor, etc.—the more they get a pass from Democrats on practices that hurt poorer Americans. **Worst of all, the more that interest groups within the Democratic Party quarrel among themselves, the more they rely upon loathing of a common enemy, white Republicans, in order to stay united*
