I took a like journalism 101 course in college as an elective, and we had a couple lessons on this. One of them, the teacher gave us a bunch of websites and was like "Tell me which of these are legitimate." Some were crackpots, some were satire, some were just weird news. When we went over the assignment in class, we talked about strategies for figuring it out.
I think a lot of people never had that class, or they slept through it.
Sometimes I'm really optimistic about humanity, but sometimes I remember the stupidest kids from school. No attention span. No curiosity. A lot of them are probably out in the world making decisions right now.
I don't know if that's exactly a Venn diagram that's a circle, but I think if you lose all the conservatives you also lose the capitalists. Whoever you'd have left would be amenable to change.
