Igbos are not the only ones whom the existence of Biafra will affect and so anyone telling non Igbos to keep quiet, not have an opinion on it or “stop taking panadol for another man’s headache” needs to realize it is not just about Igbos though they get to decide if they leave Nigeria at any event.

after the Hausa vs Yoruba clash at ife,only yorubas were arrested including an oba,they're still unjustly detained till today plus many other problems affecting the yorubas but you hardly see them agitate or discuss their problems rather they would be moving from one igbo thread to another spewing hatred over what is not their concern. a famous sage said that "an unexamined life is not worth living"
