> learning about things that might change their views in substantial ways

The core problem is that the only people who have any interest in teaching about those things are doing so specifically because they want to recruit others into their political camp. "Education" is conflated with agreement with someone else's conclusion.

(And even then, sometimes they disclaim responsibility, and just seek to morally bully you into agreement.)

Often, you already know about the thing, and this knowledge hasn't changed your view; and then the people who call you ignorant of the thing are just annoying. Sometimes, you conclude that the thing has been completely misrepresented anyway.
