Indo-European is a linguistic designation, not a racial one. Finns are completely Europid (white) racially, and the late great anthropologist Carlton Coon classified Finns as mostly Nordic. Finns are more closely related to Indo-European-speaking Scandinavians than Scandinavians are related to Indo-European-speaking Indians.

Languages get spread across racial divisions very easily through conquest, trade, etc.

Half the population of Iran is not Iranian, but Arab, Kurdish, etc. Persia changed its name to Iran in an attempt to capitalize on the "glamor" of the "Aryan" theme.

The racial theories of the National Socialists were pure pseudo-scientific crap, just like other doctrines of various flavors of socialism. Although the Nazis demeaned Slavs and glorified Nordics, there is a heavy Slavic component in the German population, and Germany is far from being the most Nordic country in Europe.

I don’t think I said anything that contradicts anything in your post. I agree with all your points.

You seem well read on this subject and coming to reasonable conclusions, so hopefully this doesn’t seem like nit-picking, because it’s meant only to add to your mental picture of the physical anthropology of Europe. The Finns, genetically, are about 25% Siberian, not including the Swedes long settled there. I’m afraid I don’t have a link for you, but will search my browsing if you like, and may turn it up before you’re able to through search engines. I just came across that factoid recently, randomly.
