We are constantly made aware of a human’s capacity to hate anyone who isn’t just like them, or anyone with whom we disagree. Martin Luther King Jr. dreamed of a colorblind world, but it was just a dream. As long as we continue to perpetuate the belief that we are more valuable than someone who is different or has different beliefs, the hate will continue.
The only answer is to teach our children that everyone has equal value, whether white or black, Hispanic or Asian; gay or straight; Christian, Jewish, Muslim, atheist or whatever religious belief or non-belief; rich or poor; highly intelligent, average or mentally challenged; free from addiction or addicted to something; employed or unemployed; physically fit or disabled, fat or skinny; clean or dirty; and conservative or liberal. Children have the capacity to love anyone, with the only criterion being how they are treated. We take away that capacity by teaching them our own prejudices.
If one believes in the Bible, the only commandment Jesus gave us was to love — love God, love everyone else. If we all lived by that, what a beautiful world it would be!
