The stained glass featured a scene from America’s slavery past and therefore had to be destroyed.

Don’t we want to remember our history, even the bad stuff?

Yale Cafeteria Worker Resigns After Breaking “Racist,” One-of-a-Kind Stained Glass

A Yale cafeteria worker has resigned after smashing a historic stained glass window in Yale’s notorious Calhoun College residence hall, which is named after the 19th century white supremacist John C. Calhoun. The stained glass depicted two slaves picking cotton.

The worker, Corey Menafee, is black. He told the New Haven Independent that the dining hall window was “racist” and “very degrading” and that last month, while working an event for the college, he decided to use a broomstick to smash the window.

“I took a broomstick, and it was kind of high, and I climbed up and reached up and broke it,” he told the Independent. “It’s 2016, I shouldn’t have to come to work and see things like that.

“I just said, ‘That thing’s coming down today. I’m tired of it,’” he added. “I put myself in a position to do it, and did it.”

City police arrested Menafee, who now faces a felony charge.

The stained glass window is one of many at Yale deemed offensive by modern standards. For many years, it was concealed by plexiglass and didn’t become widely visible until after a recent renovation. Another stained glass depiction of John C Calhoun with a slave kneeling before him was altered in the early 1990s (to remove the slave). Yet another offensive stained glass image, of a black person eating watermelon, was removed from Yale’s main library in the mid 1990s.
