I repeat, legal oppression only exists because of government. If you cannot see that simple truth, you are wilfully blind.
Primogeniture and entailment were government laws which enforced class distinctions and warfare -- withotu government creation and enforcement of classes, there would be no class oppression and warfare.
Government laws prevented women from owning property, voting, or having much freedom at all, and made marriage rape legal.
Slavery and segregation were the direct result of government laws. Society was integrating on its own until government stopped it and reversed course.
It's very simple: government creates laws to justify its oppression. You claim to get your history from the People's History. It's not much of a history if that single lesson doesn't come through loud and clear.
