Incoherence and inconsistency are features of Fascism.

The term Aryan originally meant something completely different. Its origin started in the Vedic period by Indo-Iranian people in India. The word was a self-designation and ethnic label that referred to the noble class from the Āryāvarta parts of India. The Nazis, however, linked the word 'Aryan' with the German word 'Ehre', which means 'honour' and therefore, used 'Aryan' to depict their image of 'the honourable people

Their entire concept was stolen from India including the swastika. There must have been an attempt to claim Aryans as Germans and it's they who migrated to India, so as to alter the history.

The Aryans were originally from Europe. That's why Indians speak Hindi, which is an Indo-European language.

It's a classic example of something being manipulated to create division and from that power for those that seed those lies.
