Updated: In this short clip from Hillsdale College’s free online course, “The Great American Story: A Land of Hope,” Professor Wilfred McClay unpacks how we should remember the role of the explorer Christoper Columbus. Rep. Brandon Gill of Texas has triggered a whole bunch of lefties for simply writing a tweet.

The first full lecture from this course is also available on YouTube. Find that and more on Hillsdale Studios’ YouTube.

Rep. Brandon Gill’s tweet:

The Gateway Pundit, asks… “When did it become controversial to celebrate Columbus Day and Christopher Columbus?

“At some point in recent decades, the left decided that Columbus was an evil figure, who is responsible for the deaths of any native Americans who ever crossed paths with him. Of course, what it’s really about is their hatred of Western Civilization.”
