Yes, the conception of a nation as just a geographical area and a democratic government slapped on top is I think a product of the modern period's colonialism, resulting global empires such as the English, Spanish, Portuguese, and to a lesser extent powers like France, and existing nations like the United States that don't have those long histories and relatively unified ethnicity. In that sense, premodern states were effective ethnostates.

I'm using the word in the modern sense since that's how we use it today because it helps people (including myself) who were confused by the concept of national socialism in a postmodern world that doesn't see nations that way colloquially anymore.

I'm hypocritical in my distaste for the use of the word neoliberal in such a way that it represents an effective growing of government while pretending to do the opposite by reducing public services. I recognize that that is how it is come to be known now, however.

Something a lot of leftists don't seem to realize is that the social liberalism is just a tool for the destruction of capitalism. In every example on record they'd open up to degenerates until they're in power then they call that behavior anti-revolutionary and crack down. Every time. I could see a winning ideology that proposed socialism but also was against the absolute degeneracy of the Weimar Republic being tempting for communists who want to get closer to socialism and see what the Weimar republic showed them as capitalist decadence and decline suggesting all capitalism was about to collapse.
