If the cause is “just,” the facts don’t matter to the social-justice crusaders. Case in point: The National Organization for Women just gave yet another award to Emma Sulkowicz, a k a Columbia University’s “Mattress Girl.”

Sulkowicz infamously carried her mattress around campus for months on end to protest the school’s supposed failure to discipline the student she claimed had raped her.

Problem is, the facts never remotely backed her up — starting with her texts and Facebook exchanges with her “rapist” before and long after the night in question.

Yet that didn’t stop NOW from giving Sulkowicz its Woman of Courage Award, “for having demonstrated personal bravery in challenging entrenched power and in carrying out action that has the potential to benefit women in general.”

This comes on top of her 2014 NOW honor, the Susan B. Anthony Award for “inspiring students to question rape culture.”

Back in the real world, Columbia and the NYPD both cleared the accused assailant, Paul Nungesser — who’s now suing the school for failing to protect his reputation from Sulkowicz’s false allegations.

Plainly, the real world doesn’t matter when it comes to raising consciousness.
