It just goes to show that everyone is vulnerable to misinformation. If we want to claim to be well-informed, we have to question everything - even (or especially) the stories that reinforce our existing beliefs.
The beliefs we hold by analysing information may not be the actual state. The only thing a blank slate logical mind can do is that to think a bit, verify multiple sources and get to a conclusion. Multiple sources points to different views having some reasonable practicality. Blank Slate refers to a neutral unbiased mindset.
