Prince was a very good musician and talented entertainer. He influenced popular culture and, for better or for worse, made the likes of Lady Gaga and Nikki Menaj and Bruno Mars and Justin Timberlake possible. He was a flashy dresser. He did some good things with his money and helped some causes he thought were important. He died 30 years too young for an American male of his age cohort and background.
And he probably believed some pretty strange things, being a person with the kind of compartmentalized brain that let him be a practicing JW and also do what he did did in the studio and on stage.
I am not sure why people look to celebrities with limited education for coherent information about world affairs, politics, science, history or any other subject outside their field of expertise that requires serious study.
I know a lot about global issues, political science, human history and international development. I know almost nothing about composing music, advanced math, chemistry, engineering or astrophysics. I would sound like an idiot if asked to comment in detail on the mathematical calculations needed to land a rover on Mars, why plastic is toxic to the environment, or how to write a song that will be a hit. Similarly, Richard Dawkins is an expert on evolutionary biology. He is not an expert on women in politics, feminism or gender studies and sounds like an idiot when he comments on those topics.
Prince, like most people, sounded like a complete idiot when he talked about topics he had no expertise in. And, like many people with little formal education, he believed stuff that is not accurate or true. Surprise, surprise.
