In an op-ed in The Wall Street Journal ironically headlined We Liberals Need Self-Criticism, Ioannis Gatsiounis, a writer who reports on race and politics, called for an end to Progressive-Democrats’ (whom he thinks are “liberal”) practice of identity:

[S]top obsessing over identity.

But in the very next sentence, he went right back to identity politics:

We can and should support policies that benefit disadvantaged groups, from criminal-justice reform to a higher minimum wage and affordable health care.

Pick one: either liberals Progressive-Democrats should stop obsessing over identity—stop singling out some groups of Americans for special treatment—or they should continue singling out some groups of Americans for special treatment—continue their identity politics.

Unfortunately, the 21st century segregation of identity politics is at the core of the Progressive-Democratic Party’s ideology.
