My favorite example:

Tasawaq (northern Songhay, Niger) originally had yo "camel", yoyo "camels" (yo is a plural marker)

yoyo became a singular.

So now we have yoyo "camel" and yoyoyo "camels"

Tl;dr: fascists are losers who demand to be taken seriously and they view sciences as a source of legitimacy, so they like to dress their BS ideas up to look sciencey and that's why when you look at fascism you will find pseudoscience.
