That is the inscription—in large letters—posted on a big window on the ground floor of Columbia University's Lenfest Center for the Arts; it is located at W. 125th Street between Broadway and 12th Avenue.
The Lenfest Center for the Arts is flagged by Columbia as "a dynamic new hub for cultural and civic exchange in Upper Manhattan." Its goal is to "strengthen local partnerships while highlighting contemporary scholarship, global perspectives, and compelling voices of our time."
So this is the message—"God Loves Gay Porn"—that the Ivy League school says contributes to "cultural and civic exchange" and "contemporary scholarship." The bar doesn't get much lower than this.
Imagine paying $60,000 a year to get an education like this? There must be a lack of street artists in that neighborhood.
