First.
The slave trade brought African slaves to the New World. The only major difference between Islanders, North Americans and South Americans is where the boat stopped off.
There's no functional difference between a Brazilian, American, or Jamaican Breh who's ancestors were enslaved.
All of us are encased in some European cultural schema. We want to feel like we are rebelling against colonialism, but our very speech and lifestyle is Europeanized (whether British, Spanish, or French).
The idea of conquering the colonialists is absurd. In the USA, us being 13% of the total population and not being in control of ANY significant military force, means that our "revolution" (read: violent uprising) would only result in our total destruction.
Please read Art of War, or watch a 7 min YouTube break down of it before you fix your fingers to argue that point.
All we could possibly do in this situation is to carve out our own little square within this crazy world. We will not rule the Earth.. yet.. but we CAN rule our little bubble (once we establish said bubble).
Think of the Honey Badger. Not King of the Jungle, but certainly king of his little territory. Even the KANG!!, the lion, even the lion give the honey badger six feet of personal space when they interact.
Cause Honey Badger is not playing. Not kidding around. Not playing the radio. Just pure thuggin it. At every opportunity.
All black people globally need to unite. But as a first step, all descendants of African slaves need to recognize our need to unite under that umbrella. Once we form New World Black Voltron, then we can link with African Voltron and Asiatic (Black folks in Eurasia) Voltron.
