St. John’s — New York’s largest Catholic university — has gone woke and no longer refers to Monday’s holiday as “Christopher Columbus Day’’ in honor of the explorer hailed as a devout Christian. Some Italian-American civic leaders and alumni are now ripping the Catholic institution for dissing the famous but controversial Italian explorer.

“To not acknowledge Columbus is insane,” said Angelo Vivolo, president of the Columbus Heritage Coalition. “Of course it’s an insult.” Former Brooklyn state Assemblyman Peter Abbate, a St. John’s alum who earned a bachelor’s degree in history and political science, agreed.
