Abrahamic religion isn’t set in stone, it’s capable of reform and has even done so in other historical contexts. This doesn’t even require secularism, all it requires is that they read their books in a different way for different interpretations.

But secularism isn’t impossible. As the colonizers become less secular and more religious, the historical currents begin to push against religion among the colonized. Perhaps less so among Muslims because they can deflect the contradictions onto sectarianism against the Christian colonizers, but African Christians will have to reconcile the contradiction between their anti-colonialism and worshiping the god of religious colonizers.

Or they’ll convert to Islam. It’s hard to say.

But there are lots of ways this can play out.
