A Columbia University protester who infamously demanded “humanitarian aid” and “a glass of water” for violent anti-Israel occupiers earlier this year is now teaching a class at the Ivy League school that undergrads are required to take.

Johannah King-Slutzky, a Columbia doctoral student, is set to instruct a “Contemporary Western Civilization” class at the Upper Manhattan campus this semester, according to a course list obtained by the National Review.

Classes for the course she is scheduled to teach are apparently held in Hamilton Hall, the same historic building protesters broke into during April’s chaotic demonstrations that forced the entire campus into lockdown and resulted in dozens of arrests.

King-Slutzky was thrust into the spotlight at the time when she stood on the steps of the academic building and boldly decried the university’s treatment of students involved in the tent encampment protests.

“It’s ultimately a question of what kind of community and obligation Columbia feels it has to its students,” said King-Slutzky, who was acting as spokeswoman for the students.

“Do you want students to die of dehydration and starvation or get severely ill, even if they disagree with you? If the answer is ‘no,’ then you should allow basic … I mean, it’s crazy to say because we’re on an Ivy League campus, but this is, like, basic humanitarian aid we’re asking for.”

She added, “Like, could people please have a glass of water?”

The course King-Slutzky is slated to teach at Hamilton Hall — an eight-story academic building named after founding father Alexander Hamilton — is among the five “general education requirements” undergraduates are required to take.

Meanwhile, her dissertation focuses on “fantasies of limitless energy in the transatlantic Romantic imagination from 1760-1860,” according to her bio page on Columbia’s website.

“My goal is to write a prehistory of metabolic rift, Marx’s term for the disruption of energy circuits caused by industrialization under capitalism,” the bio page reads.

“I am particularly interested in theories of the imagination and poetry as interpreted through a Marxian lens in order to update and propose an alternative to historicist ideological critiques of the Romantic imagination.”

The Post reached out to Columbia about King-Slutzky but didn’t hear back immediately.
