The most iniquitous thing among humanity is self destruction and self hatred. Being your own enemy sounds impossible but it is wilfully in existence among human beings.
When we talk about being your own enemy, it encompasses hating your own kind and this is very widespread among black people. Most black people, either from different nations or same nation do not get on at all.
Let us look at our immediate social surroundings, work places, schools and universities as well as our communities, the very people actively pulling black people down the ladder of success is our own people. (I call this inner racial hatred).
