Nigeria is democratic state with a presidential system of of government theoretically.while in practice,it is unitary state with autocratic system of government.
I consider this as hate speech which is not patriotic to the image you represent for your nation that's if you're a Nigerian, why do we consider the common things as a big issue, in fact the painting we give it is even worse than the real situation, i will advise you leave politics for those in it and let them perform all they could as nothing is parmanent, read about the political history of other countries and you will appreciate your country in many ways.
