1. Well the US (ie the state) was founded only for Europeans. Exception being Blacks of course, who didnt get a choice in coming over. So I don't think they gotta gtfo.
And while it may not have been only for Europeans, that doesn't justify the immigration we see. Blacks and Natives being around doesn't mean we give it up to newcomers who have even LESS of a claim to the land (and will not care for natives or blacks at all)

2. That's kind of the issue I harp on. Western Values are impossible to define. Many contradictory movements and exceptions. So I think protecting the phenotype is more efficient and safer than me arbitrarily deciding what our values are (which will just be revised later by someone else or if attitudes change)

3. You will be offered money to leave I imagine. Whether you do or not is up to you. In my most recent video I actually just argue for defending and promoting eurocentric demography rather than moving people around for 'purity'
Because otherwise we do get into "how do we avoid violence" territory.
As it stands, America is de facto segregated and we would have plenty of white spaces by removing legal issues in the way of free association.

I hope that helps. No problem
