Inequality has always been a minority and majority issue. In southern Kaduna for instance, the scores that have been killed, displaced and injured for practically no reason are minorities and suffering people. Their status in the society has made their pleas fall on deaf ears.
However, the main tool the oppressed have used to speak out is protest such as the Black Lives Matter protest. But governments in many countries like the US and Nigeria have attempted to stop these protests. Sadly, protests still will not stop if practical solutions are not provided to liberate people from these discriminations.
