just posting the communist manifesto is not very insightful, as I said there was a huge amount of theorizing that took place after marx, to the point that even in his life marx would say in a letter in reference to another writer, "if this is marxism, then I am not a marxist" something like that anyway.
Are you comparing Macron and Putin? It is understandable for eastern europe to react against the failure of stalinism by looking to strong leaders. My explanation is simply that America and Britain did not experience this early and aggressive revolutionary marxism, they adopted republicanism and democratic constitutional monarchism (or whatever you call Britain's political system). You say it yourself, eastern european nations are POST marxist, the anglo sphere is not, they are just now getting around to it.
With regards to france, I think their communes were rather short lived. France does not seem especially skeptical of progressivism, or particularly traditional to me. Macron is a consummate neoliberal, and parrots many progressive talking points. Not sure where you are getting his disdain for "this ideology"
You are correct that I am conflating neoliberalism and marxism! Read about Machajski, understand that ideologies evolve, don't send me more quotes from the communist manifesto, written decades before even the paris commune!
