Religion is a choice. Before the advent of the Europeans, Africans had their own Religion. Christianity; Islam; and others are all imported. They came to condemn our African Traditional Religion.
But when you look at this issue critically, it has nothing to do with Religion. This is sheer African Bullet Deflector. It is a science of its own. This work in the same way with magnets. The Force is there, but you can not see it. It is neither a medicine nor fetish. It is just a product produced to serve a need. Nothing more, nothing less. Do not drag Religion into this matter.
