THE DISCREPANCIES WITHIN NIGERIAN! ANY WAY OUT?

VIRTUALLY all the tribes in Nigeria compete against themselves in all ramification. The Yorubas see themselves as Yoruba, not as Nigerian. The same with the Ibo tribe and the Hausa too were not left out.
Outside Nigeria, we are being regarded as one. if an Hausa went out there to do something good, or commit a crime, No one is going to refer to him as an Hausa man but a Nigerian. The same with the Ibo and the Yorubas. Why is it that despite all of these, we never see ourselves as brothers?
I once had a discussion with a fellow Yoruba like me concerning politics, i said, i think the ibo too should be given a chance to prove their prowessity, the guy quikly said, are those one tribe, are they part of us? they don't even know how to play politics. uh-uhhhhhhhhhhhm. tell me who the ibos are: NIGERIAN.
Until we realise that we are one, we may find it difficult as a nation to move mountain.
God respect something in the kingdom of men and that thing is unity. in fact, when the world unite to build a strong tower to reach unto heaven, God himself said something which baffles me and that thing is:"And the Lord said, Behold, the people is one, and they have all one language; and this they begin to do: and now nothing will be restrained from them, which they have imagined to do. Go to, let us go down, and there confound their alanguage, that they may not understand one another’s speech"{gen.11: 6-7}. God himself knew that when we unite as one, we shall do all thing as we desire.
the book of psalms 133:1 said: "oh how good and how pleasant it is for brethren to dwell together in unity".
we are one Nigeria. the ibos are my brother, likewise the hausas.
tomorrow, i should be able to enter any of my brother's house with pure mind without any fear of hatred or inferiority of whatever form we are. we together made up this nation called NIGERIA.
one love my people.
