OK, OK...first I had to look up your age on your profile page... lot younger than I thought.what am I ignorant of? What history did I talk about learning?
i don't think all of our history is bad. For example I think freeing the slaves was a good and right thing. However I don't agree in the way they were just thrown onto society. We didn't do that with the Indians who were oppressed so why did we do it in that case?
if you want to talk specifics then be specific. Don't go for one liners
As to slaves, your views seem similar to many abolitionist, pre Civil War. The general thought was to free slaves and send them back. Take a look at the history of Liberia.
Now as to ignorance, you seem to believe that everyone coming to America all got along and spoke English and celebrated the same holidays and went to Church together...until the 1960's. This wasn't the case. Perhaps I'm not exactly sure what you think transpired in the sixties to make things change for the worse, or how you thought things were.
