The devil’s in the details — and so is the racism.

Zohran Mamdani shows New York where his priorities really are in his position papers, where he promises to “fix” the city’s property tax system.

His solution: Punish whitey!

According to his campaign platform, he would transfer the tax responsibility from homeowners in the outer boroughs who are taxed too heavily to wealthier and predominantly white neighborhoods.

How will he do this?

Well, once elected, he would “push . . . assessment percentages down for everyone,” which, like most of what Mamdani proposes, is highly unlikely.

But never mind that!

Next, King Mamdani would “adjust rates up” — based on the racial makeup of a neighborhood.

The plan would “effectively lower tax payments for homeowners in neighborhoods like Jamaica and Brownsville while raising the amount paid in the most expensive Brooklyn brownstones,” his website says.

So what percentage of paleness classifies a neighborhood as white?

A plurality?

Fifty percent?

Guess that means Williamsburg, which is 57% white, will have to pay, but not Astoria, where Mamdani lives, because it’s 48%.

Maybe he’ll go door-to-door to root out those nefarious Caucasians and make sure they pay the white tax.

Mamdani could have proposed property tax fixes that focused exclusively on valuation, but that’s not what his campaign is really about.

It’s about identity politics and a “hierarchy of oppression.”

Did the rich white liberals who helped him win the Democratic primary know he would turn on them so quickly?

Sorry, Zohran — we need a mayor for all New Yorkers.
