A racist note sparked protests at a Minnesota college. The school now says the message was fake.

The hate-filled note was allegedly found on a student’s windshield on April 29, and it contained an ominous warning:

“I am so glad that you are leaving soon,” the message said. “One less n‑‑‑‑‑ that this school has to deal with. You have spoken up too much. You will change nothing. Shut up or I will shut you up.”

Days of demonstrations against hate speech and canceled classes followed at St. Olaf College, a liberal arts school in Northfield, Minn.

There was only one problem: The note, as it turns out, was fake.
