Unhinged leftists interrupted a speech by columnist Michael Knowles entitled “men are not women,” with the resulting fracas leading to one protester being tased and arrested after a noxious substance was thrown at Knowles.

The event took place last night at the University of Missouri and was hosted by Young Americans For Freedom.

Hecklers constantly interrupted Knowles’ speech before he responded; ” I know, you’re so oppressed, my dears. I know, life is so hard for you. You have to live in the richest, most equitable, most just country in the history of the world. You have to get a college education; you have to voluntarily go to lectures; it’s so awful. I can’t imagine.”

Some of the protesters began to leave the venue, prompting Knowles to tell them; “People who are in war-torn nations; they must truly pity you. Goodbye. Goodbye.”

A masked leftist then tried to attack Knowles with a substance that he said was designed to smell like bleach.

The leftist was tackled and then tased by police after he began resisting arrest.

Wow Republican @michaeljknowles was attacked by a masked leftist that shot an unknown substance at him during his event in Missouri. Police took down the attacker and other leftists had the audacity to scream "hands up don’t shoot" at officers. Lunatics! pic.twitter.com/AGNoNg2fJS — Robby Starbuck (@robbystarbuck) April 12, 2019

“I know. I seem so hateful. You guys seem lovely and sweet. You guys seem so compassionate and lovely,” Knowles told the other protesters.
