All worldviews (views of the world) fall into one of two categories – either people see the world as being a loving or hating place – now it’s the nature of man (particularly men) to desire that everyone should see the world the way they see it (for the ego identifies with the person’s mind, which identifies with their perception of events, hence, inseminating one’s mindset to others, is seen as “conquering” others; which is why, apart from Judaism, every religion seeks to win converts;) hence, those who love, desire everyone should see the world as a loving place; and those who unfortunately (due to their negative experiences) hate, desire that everyone should see the world as an evil place, hence anti-Semitism, bullying etc. which boils down, to the above mentioned issue.
