Yes, a lot of voters need to stop thinking they know more than they do. Voters need to be more open that they're completely wrong about what they think they know. They have to be open to the idea that what society currently is doesn't have to be this way. A lot of beliefs that people have are quite frankly based on bullshit. I think a lot of people believe things, because some person they respect told them it was true or out of a form of tribalism. It's not, because they were seriously considering all the alternatives. However, you should question everyone, including what your own intuition says. If you're very honest with yourself, you would probably admit that your intuition has been proven wrong before.
