Can anyone say it will be unfair if the Igbos start killing the northerners in the south
Yes it will be unfair, because you don't know who the perpetration are! They might not be boko haram, just like the christian man (former armed robber) who dressed like a Muslim to go and burn down a church, they could be some other group hiding under the boko haram name.
I say let us exercise restraint and dig deep to bring out these fools trying to turn Nigeria upside down.
We all have a part to play in what Nigeria turns out to be tomorrow.
Remember it is always the beginning of a war we determine, no one can determine the end.
Anarchy is not the solution - beware.
