Kirk observed that Jesse Farrar must have been joking with his apparent endorsement of waterboarding students to death, but Farrar insisted that "I am not joking."

A liberal journalist and podcaster declared in a Twitter exchange Wednesday night that professors should drown conservative students instead of just grading them harshly.

Jesse Farrar, a former contributor for Deadspin and Vice, made the comment in response to a tweet from conservative activist Charlie Kirk calling attention to the anti-conservative bias in college classrooms.

"I get countless of messages from students who say professors are lowering their grades & penalizing them for being conservative," Kirk remarked in his original tweet.

"Leftists dominating higher education represent a grave threat to our country & culture, he added. "Conservative students shouldn't be targeted for disagreeing."
