Although hate is a disease from which no one is immune, each person has the volitional capacity to choose love. Genuine love—unconditional love—is looking into each other's hearts and imagining the best ways to practice compassion, then going the extra mile to fulfill the need.
When one truly loves, there cannot be any space in that person's life for racism, classism, tribalism, or elitism. Competition, contention, hate, violence, and indifference cannot co-exist in the heart that is filled with love.
We should treat everyone with dignity and kindness, not because they deserve such treatment, but because we deserve to experience the freedom that comes with the knowledge of having done the right thing.
