I feel those are generalities and do not actually address the underlying fundamental trigger mechanisms that release these conditioned responses.

One most consider that these urges are most primal, although excessive time not spent on surviving, would inevitably in my opinion lead to 'overblown' delusions of grandeur that lead to what we describe as ego-centric.

But, when we consider the impulsive nature of man and the inevitably, what made them do that?

We can only reflect that it was a certain 'state' of mind that is all pervasive in certain cultures.

Therefore - I believe that true peace revolves around keeping us as ethnically diverse AS POSSIBLE.
