Humans in general are social, we talk, we exchange, we learn, we develop, we judge, we fight, we disagree, we contradict, we argue and hence we coexist.
Coexistence is the terminology used for what we are currently doing and how we do it is defined by one of the interactions we carry out with the other party, ie fight, judge, love etc. We need to coexist as that’s how we get stronger, but stronger than what? is something we don’t know, is it stronger than a herd of elephants, lions, sheep or another herd of humans? The last I guess is the real deal as of now. When humans were living with animals they needed to stay together to survive in or from the wild but this scenario doesn’t exist anymore. Bunch of humans stayed too close and worked out a way to channel their strengths to a common goal like what intelligent people do to constrain the wild to a small confinement which is now tending towards non existence. Has it become a habit to stay together even when we know that there exists no imminent threat?, yes and that was again in the past but recent past. Some of these habits, good ones to be precise need to be continued but only till they result in positivity. As we coexisted and got more closer, we saw clearly the differences in us, colour and origin to start with and finally the differences in our thoughts, likes and dislikes.
When we learn more about one another there can only be love or negligence (avoiding the word hatred). Birds of the same feather flocked together goes quite well in this case. All the like minded people group together hence forming customs and cultural sets. When you are still exploring your own type, you show negligence to the so called other types. Slowly over a period of time when you realize to have enough understanding of your own type of people (tribe), the negligence to other types converts and manifests into hatred. The negative actions of how we coexist start to dominate, argue, fight, hate etc. Can this still be called socialise? Probably not, I have never heard anyone being let out of a punishment after a fight just because they were socialising.
We have come to a point in our evolution when we started to realize the differences in us is good for us and not bad. The variety brings in interest. We develop, we learn, we accept, etc. the styles of an other culture, we see benefits. Not much to exchange amongst ourselves, we know it all, what good can I bring if I keep doing the same thing, need to innovate, change the practices that have been followed, above all we need someone to appreciate us, approve us. Its a constant effort to get approval from others which helps us to overcome or forget our insecurities.
