Would people please stop using the word "genocide" when it comes to the natives; I do not believe their race was to be eliminated like they did  the Jews.  
I also think that history whether good or bad needs to be told, statues, books,  are here to stay.  Erasing all that  happened eons ago is so wrong on so many levels.  Ever since man is on this earth there were battles, the strong conquered the weak, that is just part of our history.  If for instance Britain were to take down all their statues of past royals because most of them left a lot to be desired and got into their "esteemed" positions again when the strong took what they wanted and made themselves superior to anyone else there would be nothing left.  To put it into very simplistic terms "we were all born initially equal and naked" which of course changed as opportunities arose. The natives themselves eliminated other tribes but we do not want to talk about it.  Unfortunately mankind has this thirst for power!
