ONE NIGERIA

Do i believe in a One Nigeria, ...Well i would love to believe in it but........

I must say my perception of Nigeria's tribes and ethnic groups have changed over time. I used to be very narrow minded and think Nigeria was only made up oh Igbo, Yoruba and Hausa and everyone had to fall under one category and call it a day. Anyway Glad i am very well educated and don't make such dumb mistakes anymore. Now i wonder what makes someone an indigene or a stranger of a place.
For instance, I was born and raised in Ibadan, Oyo state but if anyone were to ask me where i was from, I would proudly say Abeokuta, Ogun state. Even my last name gives it away that i am either from Lagos or from Ogun state, because of the English last name. Anyway my issue is that if i have lived all my life in a certain place, doesn't that mean i have naturalized and become a citizen of that place? Like as i was born in UCH ibadan, and raised in Ibadan, shouldn't i be said to be from Oyo state (eww) or be able to hold a political office in Oyo state?
I remember when my dad was running for Local Government chairman for Ibadan North local Govt in Oyo state. It was such a hassle because, Oyo state natives swore they would never swear in an ajeji (a stranger) . How can my father be a stranger in oyo state. His father lived in Ibadan, held a public office in Ibadan, my father lived in Ib, paid taxes , ran his business in ib and now they see him as a stranger? Now i think about people complaining about Igbo people in Lagos and how some of them want to run for public office and it seeming absurd. If Mr "Okafor" is like a third generation Lagosian what disqualifies him from running for office in Lagos State.
My mum would argue that oh its different because he is igbo and not Yoruba and a Yoruba man would never even dream of planning to run for office in an Igbo state. Well i dont know about that but i think if everyone thinks that way, then there would never be a One Nigeria.
For example Hillary Clinton, born in Pennsylvania, lived in Arkansas and then senator representing New York....... well we can argue that America is not comparable to Nigeria because of obvious reasons. So do we want a One Nigeria or was Ojukwu right in trying to divide Nigeria, I mean cos its such a hassle thinking oh, Igbo president today, Yoruba tomorrow oh hausa you've done it for too long....or what about the ijaws, ibibios, jukuns, fulanis, efiks, kanuris, Urhobos...etc when would it be their turn?

I guess my question are:
1. Can Bukola Ojo Claim she is from Imo State since she was born and raised there? Or Chinyere Okafor claim she is from Ondo state? Would she be accepted ? Can she run for state Governor without people thinking she is insane?

2. "are u from where u are born, raised, family place, or just where u pay your taxes to"? ( if thats the case I am from America oh cos men... i dey pay tax like crazy for here lol)
