Was just gonna write a fun little comment but ended up with an essay...
Turns out the only reason Wakanda has remained black for so long was just because their nigger kings have kept them isolated against the people's best interests. As soon as T'Challa died and they had a Queen for the first time in history, she learned about the white man's complete and utter superiority to their brainless baby-dicked nigger boys, and soon their "aid agreements" with the other nations turned into tributes and gifts at Wakanda's expense in exchange for white migrants coming to Wakanda to take up all the leadership- and teaching positions.
Now, the number of black males in Wakanda have drastically reduced to minimal levels after they've been shipped off en-mass for manual labour in western nations, and their women have never been happier in their lives with all the hard work in their country being done by the few black males allowed to stay for exactly those purposes.
The daily routine of every woman across the nation, including the queen herself and other nobles and warriors, consists of worshipping their new white masters out of complete and sincere gratitude for fixing their backwater nation, which for millenia had wasted their resources because they kept allowing retarded nigger boys to control it.
Even the girl who's technically still "Queen" has to prove her absolute gratitude, submission and devotion to white men through rigorous daily worship and personal debasement, all in the hope of one day earning the privilege to be impregnated with a mixed race baby, the greatest honor a lowly coon can ever accomplish in life.
One might expect that their warrior women have a greater chance to be bred for their "strong" genetics, but since even the peak nigger girl is nothing compared to an average white man, her genes make no difference and their journey towards earning that one ultimate honour is just as long as it is for anyone else, be they queen, warrior or peasant; all nigger girls are simply cock-sleeves to be used and discarded at their masters' leisure.
