Why Tribalism is Killing Africa?

I don't know any continent that is diverse as Africa. Starting from the languages, to customs, to foods, religions, etc. Traveling around will shock you. 

Living in South Africa, we have lots of similarities among the Bantus in terms of customs, belief system, and foods with minor changes here and there. However, languages have seem to be the dividing factor.

It is easy to hear a person say - that is a typical Xhosa, Zulu, Sotho, Venda, etc. Once you hear someone say that you realize they have grouped you according to your languages. Another grouping that occurs is that of the city dwellers versus rural folks. When you are in the city and act different, many people quickly tease you that your rural lifestyle sucks. However, moving from the city to the rural area - you become a star.

I don't remember hearing many conversations around stopping tribalism on media. It is one thing that media is silent on or is swept under the carpet or avoided at all costs. I won't know why we think racism exceeds tribalism.

Moving from a Zulu dominant province to a mixed languages province with dominant Tswana speakers was a biggest shock to me. I have heard time and again people say that Zulus like fighting. Zulus are this or that. Well, I wont lie history tells of Zulu warriors. But is it fair to say, all people speaking a certain language are like that?

Decoding the Bible has opened my eyes truly. That holy book is predominantly Southern Bantu languages and clearly our forefathers learned to live with each other to the point of compiling a Book written in all Bantu dialects and that Book was kept in one shared House of Prayer (Temple) - Ntlo Ya Thapelo.

Tribalism has made Africa not reach its highest potential in all ways. Yes, colonialism played a role by dividing us further into smaller or bigger countries. Also, it seemed in the past there were lots of tribalism wars which I have no idea what the causes were. 

Tribalism has meant no tribe works perfectly fine with the other tribes. Without harmony within the tribes, resources have either been misused, misplaced or unused. Other tribes have promoted their tribes without merit too. Once you get somewhere, you will here things like only Vendas work in that section, or only whatever tribe works there. African resources cannot yield the highest return because tribes turn on each other quickly once something goes wrong.

I grew up knowing that Xhosas and Zulus are not the best of friends (for whatever reasons). However, when I got to University I had Xhosa friends. Surprising enough I have met very relatable Xhosas. I am not saying tribes don't have issues but it seems these issues are our badge of honor. What caused so much animosity among the tribes - I wonder. When did we become enemies?

I really wish to know how our forefathers managed to work together and collaborate? How could prophets come from any language and no-one discriminated against that prophet. What I learn from the Bible though is that following God was the source of our success. It seems the moment a new belief system came (ancestral worship). There was no One God to unite us and no One Temple to go to - that is in South Africa though that believes in One God.
