Quakers are, without a doubt a very important part in the lineage of western anarchist and otherwise liberatory thought, along with Diggers. https://anarchy.fandom.com/wiki/Quakers

I'm about to read an article dealing with Quakers' interactions -viewed as pacifist liberalism- with indigenous people and learn some more stuff about (hopefully) why it's important to learn what we can, temper our veneration, and respect indigenous experiences.

From Westernfriend.org: "Quakers"..."were very concerned about the federal government’s policy of extermination"..."[they] wanted to prevent wholesale extermination of the tribes that had not yet moved onto reservations"..
"...[they] supported the creation of reservations where Native people would live by certain rules in exchange for goods supplied by the U.S. government. They would be prevented from hunting buffalo and required to become farmers."
