I mean, it’s pretty well documented how awful Christopher Columbus was. Even in the context of the time period: he was arrested in the new world and shipped back to Spain for a trial because he was so ruthless in his treatment of the native peoples. The myths about him being a ‘great man’ are all only like 100 years old.
Have you thought of trying to pick up another language? Started learning Spanish 4 years ago and now I can go on vacation and have conversations with locals. Also, I’m more interested in their local history because I can read it/listen to it in Spanish and practice the language at the same time.
