Actually, you won't find anything of the kind. Only if you wilfully set out to misinterpret history will you find anything like that.
Hitler came into power because he was allowed to spread his message. Because he was given chance after chance to speak. Because he was given a platform.
the argument you're presenting, at its core, is "if you dont give an evil person a chance to be evil then they wont succeed," which is correct, except how are you to interpret who is evil and who will be successful at being evil? and how do you do that fairly?
it seems to be an impossible problem to solve from my POV and removing comms from various groups willy nilly because we're too scared that humanity is too stupid practice critical thinking and not give in to evil thought is a slippery slope. there has to be other ways?
