He called me a setter and a nazi out of the blue, and I asked him if he slanders everyone or if he has a reason for saying that about me, then he replies with this legendary quote:
If you’re Amerikan, then you live in the bowels of the single most brutal settler-colonial entity to exist in the modern era. “Settling” is not a once-and-done action; it is a constant state as long as you are on settled land.
There's a lot of validity to pointing out that colonization is an ongoing process. Just ask any native tribe that's lost their fight over sacred lands so some jackass oligarch can pump oil the short way.
I'm not sure "ethnically cleanse all people with European blood" is the answer.
