Cumbo based her question solely on race — and that was wrong.

The them-and-us racial overtones in remarks uttered in City Hall Thursday by Brooklyn Councilwoman Laurie Cumbo were appallingly divisive. Cumbo, who is African-American, represents neighborhoods that have been predominantly black for decades. More recently, some whites and Asians have arrived. Cumbo worried that Asians had moved in large numbers into certain New York City Housing Authority projects.

Channeling the perspectives of residents of the Walt Whitman and Ingersoll Houses, who apparently are predominantly black, Cumbo questioned NYCHA chairwoman Shola Olatoye.

Though she wrapped her words in everyone-loves-everyone rhetoric, the point was clear: We are watching them encroach upon ou r community.

Follow the poisonous pronouns as Cumbo began: “We have a very large Asian population in our district, which we love, and they add something very valuable to our community and our district, and they are welcomed in our district.” How nice.

She went on: “But we want to understand, what the tenants want to understand is how is it — because the way they’re understanding it is that people from all ethnicities could be moving into the district, but that’s not actually the case.”

And on: “They are having challenges in terms of understanding how one particular ethnic group that speaks the same language across the board — I know that there are many different languages and many different dialects — but how is it that one specific ethnic group has had the opportunity to move into a development in large numbers?”

Recapping: Cumbo loves all her constituents, but wonders why some (they) are arriving in “blocks” where others (us) live.

Olatoye, who is also black, told Cumbo that fair housing rules and NYCHA’s tiny vacancy rate both makes group rentals virtually impossible.

Cumbo later said she hadn’t meant to offend, but only sought to understand NYCHA’s apartment assignment policy. She misses the point.

Whether or not Asians have, in fact, moved into the projects, she based her question solely on race — and that was wrong.
