Why isn't the southern strategy working while identity politics is?

Some liberals attack other liberals known as "social justice warriors" for focusing on race, or more broadly identity politics. They're accused of everything from censoring so-called free speech to claiming you're a racist if you are proud of your white privilege. It supposedly divides us by focusing on the injustices against those of color instead of merrily proclaiming we are all of one big happy family of humanity. And on and on.

A key point these self-defeating liberals miss is that the identity politics of race wins elections. Conservatives have used it for generations in what is know as the 'southern strategy,' defending poor white trash by blaming minorities for taking all their just deserts away from them due to those damned liberal policies of affirmative action etc. And it worked quite well. Twitler is using the same tropes now hoping for the same effect. By why isn't it working this time around?

The NYT reports that it isn't working because of the social justice movement. The protests about the continual killing of unarmed black men are working. The protests to reform police departments are working. The protests for economic justice are working. The protests about Twitler's hate-filled rhetoric defending white nationalism and racist statues are working. Focusing on identity politics and social justice is turning the tide against Twitler and his Repugnantan enablers and for progressive candidates and policies.

That some liberals continue to criticize this movement out of their own privileged and misguided notions of intellectual purity and abstraction divorced from political realities on the ground is tantamount to giving aid and comfort to the enemies of the very ideals they profess to support. If they want to win the upcoming elections they will realize that identity politics will achieve those victories. The conservatives have long know this but some liberals continue to shoot themselves in the foot in the name of ideology, seemingly preferring to lose while ironically keeping some sense of their own superior identity.
