Today we do that, and eat turkey.
There's more to Thanksgiving than only the US.

It's still a very common narrative that's historically been an integral part of the myth around this holiday. And it's simply a fact that the Wampanoag and other tribes of the Eastern U.S. even to this day dedicate what we call Thanksgiving as a National Day of Mourning; https://en.wikipedia.org/wiki/National_Day_of_Mourning_(Unit... A similar memorial gathering is held on Alcatraz Island: https://en.wikipedia.org/wiki/Unthanksgiving_Day
Nobody has anything to be proud of.
Nothing resembling that was widespread in precolumbian North America. The earliest similar systems I'm aware of took root in the 17th and 18th centuries, well into the early colonial period.
The continent what a slaughter show for thousands of years.
The slaves of early 17th century Iroquois were not dehumanized property like colonial era natives and Africans. This is what I meant by pointing out that the term "slavery" encompasses a vast number of radically different types of unfree servitude.
The Apache example is both not similar to Atlantic slavery, and mainly from the 18th century period where I specifically said such systems existed among North American natives.
If you're trying to make a point about the racial hierarchy within the Aztecs, the term Mexica is much more precise. If you're just referring to the slave social class within the empire itself, I can't imagine why you think it's remotely similar to colonial slavery. Aztec slaves weren't property in the sense of colonial era slavery. They had to consent to sale, only their labor was actually sellable, and it wasn't hereditary, among other differences.
