Case in point the United Nations/United States-backed Federal Republic of Somalia, which has fought a slow, grinding, but so far successful war against the al Qaeda-linked al Shabaab, banned Christmas. The fact that there are probably few to no Christians left in Somalia shows the fear the government has of religious-cultural "infection."
Meanwhile Islamist militias attacked and massacred Christians in Nigeria and Kenya during Christmas services.
Fighting back most actively against Islamism and Islam in Africa is Angola. Led by non-practicing, former Catholics, Angola has closed down all mosques outside the capital in a move described as "banning Islam." Even though Angola's leaders are not practicing Christians, they are pushing back in part with others as a pan-African push against Islam south of the Saharan Desert.
More violence in Africa is likely as faith becomes more fervent and even ideological on both sides.
