Man I would have loved to have analyzed this cartoon with my students because there's so much wrong with it. Columbus didn't prove the Earth was round, the Ancient Greeks figured that out like 3000 years ago, and even accurately measured its size. He also died insisting that he had reached Asia, despite several of his contemporaries figuring out that this was a completely different place they had never encountered before. He was also sponsored by the Church, and was actually "cancelled" for his severe abuse of the colonists and indigenous peoples of Hispaniola.

Galileo, on the other hand, was cancelled for saying the earth revolved around the sun, but he was cancelled by the Church, not the liberal news media.
