We're all descended from imperialists, alas.

Oh you may be very directly descended from imperialists, but I can hide behind the curtain of doubt. I do suppose the Igbos' ancestors displaced some of the peoples they met on their theorized journey from the Upper Nile to the Lower Niger, and who knows what former denizens of that latter place might have succumbed to genocide on our part, but nyah! nyah! there's no trail of evidence to match the cataclysmic wake of Los Conquistadores.
