In my country of South Africa, we struggled for years against the evil system of apartheid that divided human beings, children of the same God, by racial classification and then denied many of them fundamental human rights.
One of the biggest challenges is for women to find an organization that's willing to accept them back after they leave the work force to raise children without taking a cut in compensation and responsibility.
My parents really did believe in the Golden Rule. They really did believe that all people should be treated equally. They had friends of every culture, we celebrated different holidays, but really, secretly behind it, they had no problem telling me who I couldn't marry.
