Yes. Obasanjo is an example of a “de-tribalised” Nigerian. He hates poor people from every corner of the country.
A resounding majority of Nigerians are “de-tribalised”. It is just that the minority are noisier. With their noise, they elevate ethnicity beyond its proper level in the scale of importance. This takes ethnic sentiments and other primordial attitudes out of their real contexts.
Most people that are prejudiced are just mainly ignorant and chronically incapable of reason. As soon as you apply logic to the “arguments” of prejudiced folks, those arguments collapse like a pack of cards. Therefore to be a “tribalist” requires the suspension of logic.
It is not possible to be a “tribalist” and a “nationalist”, unless the nation is made up of just one ethnic group. A “nationalist” theoretically puts the interests of the nation at the top of the agenda, while a “tribalist’s” main concern is his ethnic group. Pushing the agenda of one ethnic group excludes others and therefore opens the person up to charges of discriminatory behaviour. By extension, to champion the cause of one group involves a sort of ideology which entertains notions of supremacy of the ethnic group over others. It calls for the rallying of folks from that group under one banner and thrives on creating the sort of divisions that stoke ethnic hatred. So people that cover themselves in this garb usually evolve into fascists and bigots.
Of course, I can claim to be “de-tribalised”. I never subscribe to notions that I cannot back up with logic. I am not an ethnic chauvinist, not particularly for any lofty reasons, but because it doesn’t make sense.
“Tribalism”, just like racism, is a pattern of behaviours and attitudes. Sometimes the perpetrator is aware that he is a bigot, sometimes the bigotry is unconscious and unwitting. In the latter category, people at the receiving end would be aware of this before the perpetrator.
“Tribalists” and racists are birds of the same ignorant feather. So a “tribalist” has no moral standing to condemn a racist.
It is also pertinent to note that some of the most “de-tribalised” Nigerians are members of the ruling elite. For them ethnic division is just an instrument for controlling the populace.
