Just FYI. Thanksgiving is the original blatant Cultural Appropriation. Thanksgiving was one of 13 harvest feast that the Native Americans in the area would hold each year. That's one of the reasons that Canada and The US celebrate it on different days.
We also stole most of their constitution, except the bit about "no law shall be passed that doesn't directly benefit all the children of the next 7 generations."
They had existed relatively stabley for 25,000 years, and we fucked it up, stole what we wanted, and trashed the rest.
