Those who refuse to learn from history are doomed to repeat it. Those who try to prevent you from speaking honestly of history hope to repeat it- from the "winning" side.
It's why comparing people who share characteristics with Hitler to Hitler is greatly frowned upon.
If they can make you feel guilty for noticing the similarities, they can shame you into silence. Until it's too late.
Obviously, few politicians alive today have approached the body count of Hitler or other dead tyrants, but it's a matter of scale, not character. Given the opportunity and popular support do you doubt any US president (or "serious" presidential contender) of the past 50 years would have had the principles to not become a Hitler? Do you honestly believe the next president- whoever it might be- would have the character and principles to reject that kind of death and destruction if "the people" became convinced it would make them "safer"? If so, I don't think you have learned from history.
