Karen is larger, but black girls win fights more a lot of often. This is my observations. They fight savagely and more brutal. They are better technically more often also.
Maybe therefore, that they come from locations often, where they have to can fight. They have stronger bodies also. This is visible. Times of slavery in USA - stronger human have the larger chance on survival. This is a genetic. Therefore the fight will be very closed. To show victorious girl hard. Hmmmm..... However Freemma will win.
