What you do is offer a pathetic sleight of hand with the appropriation of the term socialism by fascists to mean completely different from the mainstream definition of socialism which is Marxian.

Nationalism has existed since the nation state

Nationalism didn't become a school of thought in the 20th century

It has been around forever

How long has the nation state existed? Since the 19th century, with few exceptions.

That is a Cultural Marxist view constructed to delegitimize the nation state

Nation state has been around since the agricultural revolution

Except it hasn't.

Name one.

Egypt

LMAO

China

Terrible example, because it's false.

China???????

Those are not nation states.

Persia

wtffff

these are all nation states

Stop, let me address how you're wrong one at a time.

they have an authority and border

Egypt's identity was religious and shifted through time, the nation was embodied by the dynasty.

no

Persia really has no national identity.

Yes. You are simply blatantly wrong.

those are or where nations

Persia was routinely conquered by foreign entities.

routinely

no

There was no national identity to speak of.

Yes, routinely.

Muh nations came around in 1850

no thats not a thing

Jalayirids, Mongols, Gokturks, Oghuzi Turks, Scythians.

Persia has repeatedly been conquered.

look at european empires

they had nationalism for as long as they where around

look at mercantilism

Mercantilism was based on the acquirement of resources.

Has nothing to do with nationalism.

How about we start by you defining what a nation state is because it clearly is not what an actual nation state is if you think Persia and Egypt and China were nation states.

France was not even a nation before the French Revolution. It was numerous languages and *communal* cultures. People did not speak "French" outside of the Ile-de-France.
