If people were open minded, did learn from history, would question and search for answer it would help. The fact is most do not care. Another fact is people are easily fooled and not flexible. Their emotions take over and emotions are the worst guide one can have. The fear for what might happen. That's what emotions are about.
Every psychologist can explain how fear affects the brain. It's like talking to a deafman's ears which is exactly the reason why so many fall for it, the cattle follows the leader and they shout, get hostile aggressive if you show proof. Atupid people are a threat to each community. They make polarisationand genocide possible.

If there's a vaccine for a killer virus and if I take it why should I fear to drop dead? That javb saves me or? Apparantly, people don't think this way. They stick in their world filled with fear, common sense left them long ago.

We had all kind of plagues and witch hunts, genocide world wide but if it doesn't affect you it's not interesting.
Today nearly everyone has internet. It's possible to search worldwide. Each language can be translated but hardly anyone does. Too much trouble. It's easier to believe what they say. Whoever 'they' may be. 🍀💖
