Racism is like a disease that has eaten and is still eating the systems all around the world. It's been years of brainwashing and mind control. A system that oppresses and reduces a group of people to nothing regardless of their abilities.
If everyone looked at others as equal regardless of color or tribe, the world would be a better place. The feeling of inferiority births racism. So, teach your children self respect first, respect and compassion for others. Let them learn to stand tall and stand for what is right.
The key to the problem is in the younger generation. They need to be taught about the might and power they posses. Hence, nobody can make them feel inferior.
