When studying history, I sometimes wonder - how certain things could have happened? Some of these seem ridiculous or unbelievable when you look back. Now I know how it happens. Some people do something strange, then their number increases, they are very vocal, they're 100% sure what they do is right, they're very emotional about it, and at a certain point it seems like they are the majority. They do certain things like revolutions, usually with a bad result, and you can't do anything, you can just watch it powerlessly and hope it doesn't end badly this time.
