It is amazing that they don't remember the invaders for a lot worse.
After Cortez, De-Soto and the comquistadors, the Native American populations were devestated by the introduction of European diseases.
Measles were fatal to a population with no aquired immunity from generations of exposure.
I thought it odd that European diseases were so devestating to the Americans.
But there appear to be very few diseases of such scope the Americans introduced to the Europeans.
By the time the English settlers started establishing colonies, the Native American populations were a fraction of what they had been.
The Indian resistance may have been more formidable had this not happened.
Like the Neal Young song, "Cortez, what a killer."
Whatever works, use it.
A good idea stands on its own value independent of authorship.
If it stands or falls on the credibility of the author, maybe it isn't such a good idea.
