Human beings are group-living animals - just like pack animals. Since the human beings came into the world - whenever their “birth” was - they have been being such group-living animals (naturally) and group-living humans (culturally). So it is very difficult for them to not differentiate themselves from others, especially from other group-living animals (naturally) and group-living humans (culturally). They can not give up their attitude of “we-are-not-them”, “we-do-not-want-to-be-like-them”, “we-are-against-them”, “we-fight-against-them” and so on.
