The Ottowa’s were cannibals. The Illini weren’t as far as I know. Some tribes practiced the long pig thing some didn’t. Mostly the further north woodland tribes did. It nay have been a custom left over from when they were hunter gatherers and cannibalism was a significant way to avoid starvation.
Leftist ass-hat belief structure: create a disturbing paradigm that, if true, has to apply equally to all citizens, but imply that for an unstated reason known only to the teller of the story, it does not actually apply to them.
So while your presence is due to this violence, her presence is not. As a leftist, she is incapable of error or wrong-doing. It is just a form of magic thinking that leftists substitute for reason. And they even have a reason for not being reasonable — logic is a form of toxic masculinity.
Give thanks that you are not a leftist.
