hate and its salebility

why does hate sell more easily, cheaper, without much advertisement? (to be continued...)
OK coming back!
Well I think hating each other is intrinsically human! This comes from my belief that humans, in the process of evolution, some how began depicting animal behavior in pursuit of physiological sustenance (security, food, sex). In the "natural" animal process of survival of the fittest, there is bound to be competition for mates and food. However, we know for a fact that animals do not morbidly hate each other inspite of the competition! But we sure do. And this is because of our overly developed large brains. Therefore I say hate is naturally human. Because when humans behave like animals, there is bound to be hate. Conclusively an society which tolerates hate of any form is intrinsically uncivilized.
On the contrary, loving a person, is not innately human! We know that humans can attach themselves to other humans and animals too, however this property is not solely human. Animals love too. In fact maybe more so that humans do. This time though, our large brains keep us from starting to screw in the middle of the street. So in fact loving does take a large amount of civilized behavior on part of humans.
