To many people in todays world nazism may seem like the only available defense against the Kalergi plan and related policies but, basiclly, all racist systems are scientifically unsound.
I appreciate your point of view but you’re putting the cart before the horse. This is because the economic system facilitates those racist theories you mentioned.
Look at the US where government has so intruded upon business that it is trying to run and command business. “Bake the cake” is but one clear example.
And with the US government imposing control of business that control facilitates racist DEI policies.
DEI would not exist absent economic fascism. This is why reducing ‘Nazi’ to a mere epithet is an error. It allows the actual Nazis and fascists to operate in the open.
