Korra is really one of those feral subhumans that really need to be taught a lesson. I remember that episode where the villains chained her up and tortured her. One of the best scenes in animated history. It is too bad that the villains did not manage to break her spirit and make her an obsequious sex salve as nature intended.
honestly, Rei as had more than enough time to build her own love for White men on her own, clone or not. Still, honestly choosing between those two is more of a taste question than anything else.
