Eh sort of. European ‘conservatives’ were originally wanting to ‘conserve’ the existing social or i.e. feudalism and monarchism. American colonists were the ‘liberal’ ie for freedom. Liberty and democracy. This is where ‘classical liberal’ comes from.
This is where the flip comes because modern American ‘conservatives’ are closer to the Classical liberals because they want to ‘conserve’ freedom liberty etc, Weber’s modern American liberal want to enact new-feudalism (socialism/communism)
Thats where people get confused at the nomenclature
Structurally Marxism is industrial neo-feudalism dressed up in atheistic, post enlightenment idealistic egalitarianism.
The difference between its results and what it promises are irrelevant to its internal intellectual coherence. It’s a useful tool for tyrants to gain and hold onto power.
