Answer: It is more convenient for a person.
Question: How can we get rid of these prejudices?
Answer: We do not need anything except aspiring for a single root. No arguments on the corporeal level will help us; they will only worsen the situation. This is what all governments and international organizations are doing. They are trying to somehow unite and pacify everyone at the level of our world, but they cannot succeed.
Only rising above our nature into unity and mutual adhesion can help us. Otherwise, we will be involved in even greater arguments, hatred, and rejection.
