You need a "One Race" nation for that to occur."I have a dream that my four little children will one day live in a nation where they will not be judged by the color of their skin but by the content of their character."
Sometimes one race can fight among themselves based on skin color. Remember the Tutsi and Hutu war and genocide in Rwanda.......over being a lighter shade of black.
History shows that humans form tribes based on physical characteristics.
Tribes compete for wealth, power and dominance.
Clearly some individuals from different tribes can form good friendships.
Also clearly......TRIBES do not.......they always end in competition and warfare.
History and real life affirm this.
If God is involved.......God has shown no sign of correcting the hostility between tribes.
