I'm sorry you are offended but I don't think I said anyone thought that.
My actual statement was as follows:
"If you think we came here and there was nothing because the inhabitants were ignorant savages you couldn't be more wrong." in response to a statement to the effect that Amerinds on the eastern seaboard had some agriculture but not enough industry to be of consequence in the face of greater forces of productivity.
I think that is a valid comment in the face of an attempt to minimize the destruction the "birth of our nation" caused. The truth is America is not exceptional and the faster that Americans come to accept that fact the better the better off they will be.
