History cannot be destroyed. As long as someone remembers, or holds documents ( not a book of someone's "perception" of history ) pertaining to history, history remains unchanged. The USA was a slave owning/trading Nation well into the 19th century, that's a fact and cannot be undone. Trying to erase that history is not only impossible, it's dangerous and could lead to far reaching unintended consequences.

Germany still teaches it's children about Hitler and the evils he inspired, not to glorify any of it, but to ensure that future generations do NOT glorify that period in history, in the hopes that it's not repeated. To this day, there are people trying to rewrite that history, trying to revive the Reich, just as there are those here trying to revive the Confederate State.

We must remember all of our blemishes, acknowledging our mistakes and bad deeds. Not to apologize endlessly for them, or trying to justify them, but to ensure that WE don't repeat any of them.

History cannot be erased.............................but it can be repeated.
