Brian Keith provides motivation:
We like to pretend that genocide is something other people do- the Nazis, or the Tutsis, or the Soviets, or the Chinese Communists.
We Americans practice genocide too.
And just like those other people, we make sure our victims are disarmed before we butcher them.
The Cherokee, Muscogee, Chickasaw, Choctaw, and Seminole did not have the means to fight back against the genocidal United States.
So they died by the thousands.
Genocide isn’t something only “they” do. It’s something we do too.
