I agree that it's pretty easy to learn about but killing off curiosity and any comfort with researching things is also part of the education system and culture.

Can't tell you how hard it is to get supposed leftists to just read some Marx sometimes. I don't think that's very difficult either, it's like a few hours per week for a couple months and you're ready to go without needing someone (usually with a particular partisan bent) to tell you what it means. I then proceed to watch leftists not read Marx at all for 3 years while justifying almost everything they do in his name lol. It takes a program and hassling people and making it an inherent part of a campaign to get people to overcome these barriers. We have the luxury of hindsight and of having adopted better practices. Now we have to help others gain the same consciousness!
