So, you’re saying that we can’t trust the textbooks of today about what happened 200 years ago?
If that text book is all you have, and there is no other evidence, then it makes sense to be skeptical.
Like “Howard Zinn’s Peoples History” skeptical.
People are always ready to write their today motives into historical persons, or legendary persons.
The difference between history and legend is the history has facts, evidence, and reason to back it up. Legend has a story, but the facts are either impossible to find or impossible to believe.
Not in American schools!
