> College Democrats Shut Down Invited Speaker
Rowdy protests lead university to cancel lecture from controversial speaker
On Monday, campus police struggled to break up a large group of students who were gathered to protest a speaking engagement that was planned for Friday night. The invited speaker is a social media celebrity known for making inflammatory statements about Democrats. His posts frequently mock the intelligence of Democrats and in one recent post said that “there may be nothing more despicable or disgusting than a Democrat.”
Thought the protest, which was organized by the College Democrats was mostly peaceful, it became chaotic as students tried to pass through the protestors and enter the building. Michelle Jones, a junior at the university, said she was struck with a sign being carried by one of the students demonstrating. “I don’t know if he did it on purpose,” said Jones, “but I was pretty annoyed. I just wanted to hear what the speaker has to say.”
Ultimately, the College Democrats were successful in getting the university to cancel the event. But not all are happy with the outcome. A petition on social media is calling for officials to punish those involved and suspend the College Democrats’ ability to hold events for the rest of the school year.
