It's a beautiful thought process. The root is the lost of Identity. Forceful union. Like the post rightfully pointed out, Bangladesh and Pakistan broke away from India.

Why is Biafra not allowed to choose its own path? A nation that forcefully entrench the will of the minority over the majority of its citizen will witness continuous backwardness.

Nigeria is my home, but we need to either regain our national identity or allow people choose their own path even if it will mean breaking up.
