Are "white" people more intelligent than "black" people? Are Jews devious and grabby? Intolerance and violence through racism includes slavery, national solcialism in Germany, apartheid in South Africa, or the genocides in Rwanda and Bosnia. But racism is not only wrong theologically, it is not only against the dignity of humans, that guarantees their human rights, but newer genetic research also proves that the whole classification into races is without foundation. Biologically speaking, all humans belong to one race. E.g., when you need a blood transfusion, you should not look for a blood donor from your 'race,' but someone with the same blood group transcending all 'races.'
