All countries wash their history books to prop up those that are considered heroes and downplay the accomplishments of those considered the bad guys. For you to imply that America is the only one to do this, or even that we do it more than other countries is prejudicial. Yes we are screwed up, but we don't hold a monopoly in it. Everyone (except maybe Belgium

) has dirty laundry that they cover up.
As to the original topic, I am of Jewish heritage (even though I'm Christian by faith) and Hitler on currency would piss me off. Like most Americans I'm woefully ignorant of history (of my own country and others) and since my courses in history were extremely boring I've never spent much effort in fixing that. So while I know in general things that happened I don't know who or when they all happened.
If what you say about Jackson is true then I would agree that he has no place on our currency. What you are describing goes beyond Washington having slaves (since that was a normal practice at the time I don't fault him for it) or the like because his actions were not just maintaining the status quo but were an escalation of these negative ideals.
