Yeah I know of ACBN, I actually have the book on them explaining who is African and who isnt, so I am still learning about this like you as well. https://www.amazon.com/ACBN-Afrikan-Centered-Biological-Nationalism/dp/0578195402
And I agree, we do have dark skinned traitors as well, but we know very well and clearly that they're African. Its only in the United States they go by the one drop rule, in South Africa, UK, etc they will refer to you as either mixed or coloured (especially in South Africa). But then again, you have the Igbo people of Nigeria who produce "light skinned" traits, but none of them are looking like Obama, Kapernick, etc. To trust a mulatto is tough, you don't know their psyche, will they really go and kill their white mother/father? At any given moment they can flip sides and destroy you.
