The Norman Conquest and its consequences have been a disaster for the Angle people and the human race. Had the Norman Conquest not happened, the possibility of a proto-socialist Anglo-Saxon kingdom going on a different path to a different proto-mercantilism and proto-capitalism, giving way to Socialism with Angle Characteristics might have been possible.
Before the Norman invasion, Angle women had ancient rights to own property alongside their men. We see that the Norman invasion, the spiritual Continental-Viking pollution of Angle society, created a set of historical conditions that introduced French agnatic primogeniture and thereby reduced women to property. This is the first indignity of the Norman Conquest, patriarchal feudal propertarianism eventually evolving into capitalist patriarchy - an ontologically French patriarchy governing English women and men!
Secondly, the Norman conquest was the formalization of a proto-imperialism that forever wounded the Anglo-Saxon people's collective consciousness and distorted it forever. The Norman Conquest violently destroyed the rights of old Angle landholders. Collaborators with the Norman's were rewarded. Despite having been foreigners to the Isles just half a millennium before, their resistance of Danes and Vikings (guess what, forefathers of the Norman's!) taught Angles to resist invasion and proto-Imperialism, no matter what the coat. Yet just as an abused child grows up to become another abuser of children, by the violent subjugation of the Angle peoples paved the way for them to become modern imperialists. In the Norman Conquest, one finds the prototype of extirpation of the American natives and Indigenous Australians.
Thirdly, the Norman invasion had once again connected Angle history to the history of the Continent. Previously, the Angle evacuation of Old Anglia from climate change on the German continent had severed English historical development from the oppressive violence that was occurring on the continent, from the Holy Roman Empire's squabbles with the Papacy and from the incipient French absolutism. Just as imperialism and liberalism-capitalism need monopolies over entire continents (see the EU) to grow, so did feudalism and Roman Catholicism. Then there was the eventual entrance of the French-speaking English-ignorant Crusader king Richard who ruthlessly took from his kingdom's coffers to fund proto-imperialist Crusades rather than focusing on home English development.
Just by looking at the current state of the Anglosphere, one will understand the disaster of the Norman conquest. America, chief imperialist power, are a continental nation of Angles with Norman minds. New Zealand has been harried by fascist spiritual Norman Crusaders slaughtering 50 civilians. Merkel is as the Empress Matilda violating English sovereignty. Only the island nation, a Macro-Albion Australia (most proletarian of the English nations) is relatively unscathed and even then it's connections to the Norman-minded English is reducing it to a mineral colony, a Richard Lionheart's coffer for imperialism.
Everything wrong with modern Anglo societies are ultimately evils derived from the Norman Conquest. We must strive to "Deconquer" ourselves, to "Decolonise", "Denormanize" ourselves that we may be put back on the path of Angle socialism from which we were disrupted by this great evil. Down with Normanism, down with the New Normandy of America, Angles with Norman Minds!
Stop, Survive, Denormanize!
