Bullshit it didn’t hit full swing until the third republic the third republic was just when it also picked up the dynamic of the religious and language rights of immigrant communities because of all the colonialism the third republic was doing in Africa and the ME
Immigrant communities btw who were the actual resistance backbone in WWII, and who go unrecognized because the french right were collaborators who wanted their stories stamped out to preserve french nationalist narratives, and the french left were the backstabbing stalinists who sold them out to the Nazis before liberation came so that they’d get to take credit for all the heavy lifting post war and wanted to cover up their own complicity.
Never trust a “leftist” who thinks state sponsored murder is a good idea. They have no interest in anything except to be the executioner, and to feel nice and self righteous when they pull the trigger.
