Not to split hairs but I don’t think there’s any “amerikkka” in settlers. Sakai uses “Amerika” and yea I believe he borrowed it from other groups. My memory is a little fuzzy on the specifics, another comrade may know better, but I think it came from some black or afro nationalist orgs or other things like that. It definitely predates settlers
yeah and i believe the point is/was to highlight and draw a link to fascism with it. I remember reading a thing a couple years ago about some of the groups that began using it that influenced sakai's usage of it but tbh post-covid it's hard for me to remember random shit like that anymore lol
Amerika was fist used in the 1960s, to liken the United States to Nazi Germany, as it's the German spelling of America.
Amerikkka was an evolution of that popularised by music, magazines and books as far as I know. I know NWA and Ice Cube used it a lot in their music and promotional materials.
