How did the Nazis figure out whether a person or community is 'Aryan' or not?

If the Nazis wanted someone to be “Aryan”, they made up some cock and Bull story to justify it. If they wanted the opposite, they could be equally inventive in assigning someone to “Untermensch” status.

Poles are “ugly, subhuman Slavs” but hey, Hermann, have you noticed how hot and blond those leggy Polish chicks look? They don’t fit our “subhuman” model at all! İn fact, they kind of look like our Aryan ideal personified!

They used their “spidey sense”.

What is the dirtiest thing you have witnessed your wife do?

Ja, well, Helmut, it’s very simple. Those hot leggy blondes are actually not Slavs at all but are, in fact, Aryans who got Slavicised. We need to rescue them from the pit of subhumanism that surrounds them by immediately giving them Aryan status!

Nazi racism was not actually scientific, it was just a load of bullshit with a thin patina of “science-y” garwharbl to justify what was basically a totally ideological belief.

Ultimately, what made a group of people “Aryan” or not came down to how much they wanted them to be “Aryan”.

As a woman, what would be you response to a male friend’s offer of a full body massage?

And then we get sexy time with them!

And then we get sexy time with them?

It was all bullshit the Nazis made up as they went along. Trying to cast it in real scientific terms is a waste of time.

Why don't I want to talk to my girlfriend when she loves me a lot? I feel bored.
