The differences between us are essential to humanity. They are a circumstance of birth and should not become a source of conflict or hatred. Unfortunately though, all human beings have the tendency to disregard people that they consider to be inferior, due to preserved mentalities within their own communities or to the innate instinct of survival. Nowadays, well over one century after Darwin's The Origin of Species and the natural selection theory, our minds are still stuck in the idea that some people are weak and in relation to fitter individuals they will end up perishing. The late 20th century realities, however, show us that all peoples are unique and deserve our respect, irrespective of skin colour, religious beliefs and practices, descendance or ideas. If people manage to assume that, then we will all stand a better chance to live together in harmony, Far from vain concepts such as superiority or inferiority.
