Since you do not know much about him it would be wise to learn something about him before you start showing your lack of knowlege. So, what you are saying is that All African Religions Are Satan Worship. Thank you for telling all that you are not the sharpest knife in the drawer. "There is none so ignorant as he who refuses to learn." That also could mean Research For YOUR Self.
I am sure it was mentioned before but let me try again. In traditional African society their is no concept of Satan. However, there is Set,Sutekh/or Sut.
These are cosmological references to the Southern nations and Thrones of Ta Shemu, this is to say Upper Egypt or Nubt. (Nubia).
As the Nile Delta region became dominated by the Northerners they fought the Southern kingdoms for control, demonizing Set (the seat of power in the South) and as Christianity took root, Satan was equated with the Southern nations who retained the Matriarchial system of lineage and veneration of Mami Isis Auset Iusaas etc.
Therefore, anyone who venerates Isis Auset Maatkare Makeda Kendake Nicaule or any of our Queen Mother Ancestors is considered a Satanist according to the Northern and western religious doctrines.
