On Marxist "Scholars" Either Ignoring or Rationalizing Away (the Attempts of Which Are Borderline Comedic; the Freed Slaves Still Being Dirt Poor and so What Did the Liberators Truly Accomplish, for Example) the Hard Fact that European Colonialism Largely Ended Slavery Throughout the African Continent

This of course wasn't the sole contribution of colonialism (white Europeans also bringing medicine, infrastructure, economic growth, trade, education, reliable energy, institutions necessary for the establishment self-government, modern agriculture, etc.) but because it ties the anti-West dullards into knots it is and likely will remain my favorite.
