It’s a classic New York gentrification story with a morality twist. Think “Fifty Shades of NIMBY.”

On one side, longtime residents of a block in the Bedford-Stuyvesant area of Brooklyn, led by Laurie Miller, who lives in the same narrow house on Quincy Street that she moved into as a child in 1974.

On the other, a queer feminist, Charlotte Taillor, who moved her business next door to Ms. Miller, from a more expensive space in Crown Heights.

And in the middle: Ms. Taillor’s business.

Now about that business. It’s what’s known as a kink collective, where Ms. Taillor runs bondage workshops and other fetish events for the B.D.S.M. (bondage, dominance, sadism and masochism) community.
