Crazy to see the demeneted afrocentric fairy tales make it to the mainstream. The could just make a movie about historical black persons but they choose to blackwash everything:

The actual Carl Gustaf Emil Mannerheim was mixed Finish and German, and completely Caucasian with no sub-Saharan African ancestry.
The casting of black actors in white historical figures with other recent examples being Sir Lancelot, Julius Caesar, “Whitest of the Gods” Heimdall, Orpheus, Sir Bediverie, Achilles, Joan of Arc, Oenomaus, Margaret of Anjou, Hannibal Barca, King Solomon, Friar Tuck, Zeus, Guinevere, and Robert de Beaumont is done for the same reason that statues of white historical figures are being torn down around the world.
It is simply an extension of the persistent attack on “white identity” to demoralize the people with historical revisionism and also in part to normalize the population replacement.
While this is not an effective strategy on adults, it can certainly influence the developing beliefs in the youth, and as such is an active social engineering program by the powers that be.
