Fanon was flexible with that term, it covered Arabs and Africans living in the North, and just Arabs. He strongest distinction was between the Colonized and the Colonizer; that’s where his lines were drawn.
It’s been some time since I’ve read ‘Towards the African Revolution,’ and I don’t fall back on it as much as I do the ‘Wreched of the Earth,’ but your question has motivated me to give it another read. Thanks.
