One person was arrested after a conservative speaker talking on gender politics at the University of Missouri-Kansas City was sprayed with an unknown chemical that smelled like bleach.

According to the Daily Wire, the news outlet’s own Michael Knowles was attacked on Thursday with a squirt gun filled with a glittery chemical – initially believed to be bleach – by a masked person while giving a speech called “Men Are Not Women.”

The speech, which was meant to highlight key differences between liberal and conservative gender ideology, was hosted by the conservative group Young Americans for Freedom. The event attracted a handful of protestors who Knowles says were heckling him while he was trying to deliver his speech.

According to the Daily Wire, “Hecklers consistently interrupted Knowles and yelled at him, prompting Knowles to respond, ‘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.’”

Knowles’ response triggered a mass exodus of the protestors. This is when the masked protestor sprayed Knowles in the face and side with the unknown substance.

Police then wrestled the perpetrator to the ground as protestors yelled: “Hands up, don’t shoot.” Reportedly, officers tased and detained two protestors.

Knowles tweeted a warning to conservatives, informing his followers of what had happened to him.

He wrote, “He got me a bit in the face and on the side. At first, I thought it was paint because of the color and smell. Later found out it was bleach.”

Knowles continued, “These are the people conservatives on campus are up against”.
