You’d have a better chance of convincing the Bolsheviks to abandon class warfare on the grounds that it’s divisive and drives away the Mensheviks and Kulaks.
Asking the Democratic Party to abandon anti-White racism is like asking the Democratic Party to abandon its own ideological mythos. It’s a liberal progressive party, and the entire point of liberal progressive parties is to dissolve all unchosen obligations, inherited orders, and particular/majoritarian identities.
All of that in the West inevitably drives Progressives into becoming anti-White because Western civilization itself was built by Europeans.
In the Progressive mind, “White” simply becomes shorthand for the civilization that has be overcome in order for the abstract universal floating bundle of rights that we once called a “man” (but can no longer because that’s too gender specific) to be fully liberated.
To renounce this would be to renounce the central premise of Progressivism itself, which is the entire reason why the Democratic Party still exists in the first place. So you’re essentially asking a political movement to voluntarily dissolve itself, which is just simply not going to happen.
democrats legit need to ditch the anti-white racism, it's not quirky, it's not funny, it's not tongue-in-cheek, it's one of the major drivers of moderates/normies away from their camp
you can dislike that, you can think they're too thin skinned or whatever, but it is what it is.
