While I support the idea of people educating themselves (and I would also recommend the reading list you provided), who can guarantee 100% that they are free from propaganda or brainwashing? Especially given the vast amount of information everyone is confronted with every day. We are emotional creatures, each susceptible to misdirection by those who intended it (or perhaps even worse, by those we trust who don't intend it).

Advocating that people take themselves out of the pool because they may not understand the entire situation would eliminate every possible voter.
