Not everyone is unaware of this issue. Take two posts from black American conservative Shay at Booker Rising.
Of course Arabs living in northern Africa have a different agenda. For the overwhelming majority of them are not genetically nor culturally African, but Arab occupiers of black land. This is point lost when Arabs wail incessantly - and expect black folks to follow suit - about Israel's sliver of real estate in the Middle East. Yet if Arabs and their diaspora can call to push Jews out of Israel (their ancestral home) in order to have a Jew-free Middle East, then certainly Africans and us diasporans can call to push the Arabs out of northern Africa (which is not their ancestral home) and back onto the Arabian peninsula and further so we have an Arab-free Africa. Reclaiming this land should be a long-term goal of pan-African unity. However, I would argue that the Arab agenda is hardly hidden, as they've been trying to dominate Africa off and on for centuries.And this one:
It is great that Africa is taking more of a lead on Darfur. As an American of Cameroonian, Chadian, and Nigerian descent, I am glad that two of my ancestral countries are in the mix. My only concern is whether the allocated troops are well-trained enough and have enough firepower to take down the janjaweed. After all, this may be the reason why the president of Sudan - an Arabized Muslim government that is backing the janjaweed as they wipe out the black population - is so supportive of this peacekeepers proposal.
