I think both were extremely messed up in my opinion if you ask me. One took blacks and enslaved them. The other involved looting from Native Americans, and in the case of those who wanted settlement, stealing land from Native Americans. And those who didn't participate in slavery took it upon themselves to impose laws against blacks.
Nowadays, the former subhumans think that they deserve reparations for what their betters did to them. If that does not send you into peals of laughter, there is something very wrong with you.
Honestly, they were not considered "people" back then. Now they are, so they're okay. But they shouldn't expect special treatment.
