It’s not so much that people don’t want to learn about it. It’s more so that they don’t want to be told/believe. Another factor IMO, is that they can’t understand it, so they won’t believe it. And you can’t force people to understand something. It takes time. Think back to your days in school. Think about your favorite teacher. How did they teach you about something you had no idea about? Did they start to become unglued when you didn’t understand what they were talking about? Did they tell you to just believe it because it’s true?
