What's Thanksgiving? The holiday where you guys celebrate that you enslaved an entire continent and raped it of all its resources?
You so silly.
The story goes that the Pilgrims came over from England and were all, "Derp, we don't know how to survive here."
So the local Native Americans took pity on those poor, retarded white people and helped them grow food to survive the winter. But before the winter they had a big harvest festival with the Native Americans as guests, a.k.a. the first Thanksgiving.
Later on, we rewarded them with Smallpox, breaking treaties, and taking all their land and forcing them onto Oklahoma, the definition of "crappy place to live"
