How wrong can you be? Christianity was widespread in the Sudan, by natural evangelism, not forced conversion by Europeans, in the 2C (recall the first "militant" Christianity occurred post-Constantine).

Christianity has almost as long a history in Africa, particularly east Africa, as it does in the M.E. There were entire Coptic Christian kingdoms for centuries. The only "forcible conversions" by "outside invaders" occurred when Arab religious imperialists exported Islam, at sword point, in the 7th century. Islam has been systematically oppressing and killing Christians, animists and other "pagans, since then, with the West, for the most part, not helping them.
