In light of the English behaving like racists and demanding that foreigners not murder their children, its time to revisit language.

A country is a bit of land. A nation is a group of people. And a State is the body that governs a nation that lives in a country. These words are not synonyms! Democracy is rule of the people, ie the nation. Without nationalism, democracy is, by definition, a form of tyranny. If the nation (that is to say the people) is not in charge, then they are slaves to the state. If foreigners are given equal preference to nationals then the State is merely a tyrannical body the runs the country (a bit of land) as an economic block. The worst tyrants of the middle ages and the ancient period dindn't even try this.
None of this is true. Ethnic homogeneity is never requied for a nation. Ethnic similarity can be. Almost no nation, even tribes, are purely ethnically homogeneous. The Iroquois weren't ethnically homogeneous. Multi-ethnic nations tend to be the norm. Multi-cultural is the aberration.
Fascism is explicitly NOT ethnically homogeneous. It's the totalitarian form of CIVIC Nationalism. You're trying to avoid specifically saying National Socialism. You are advocating for a Gleichaltung of the race into a Volksgemeinschaft. To Socialize the population into a socialist racial commune. The good of the nation is purely decided by the head of the state and nothing else. All aspects of the people must be forced into accepting that ONLY the state can determine the good of the people, and any of the people who disagree or dissent must be killed or coerced by any means necessary. This includes mass migration or any other bullshit so long as that decision is made. It's why a half dozen NSDAP members founded the German Green Party. Same for why BLM supports Palestine, why the SNP supports mass migration, same with Sin Fein.
Globalism is merely a Supra-Nationalism. The greatest threat to the nation under Fascism and National Socialism, is the eradication of the nation by the state as it homogenizes the people into the state.
