The doubling down on identity politics among liberals since Donald Trump’s election follows from something like this ambition to unify non-whites against the Republican Party and in favor of the Democrats. (At the same time, the left’s growing emphasis on intersectionality, which sows division instead of unity by highlighting the distinctive, irreducible grievances suffered by the members of ever-narrower demographic sub-categories, adds a heavy dose of self-contradiction to the project.)
It would appear that the “emerging Democratic majority” requires anti-white identity politics as its midwife.
That would be inadvisable in civic terms even if demographic trends over the next half century favored non-whites more convincingly than they do. As it is, liberals risk actively antagonizing (and hence galvanizing against them) what will remain for some significant time to come the single-largest demographic group in the United States.
