What similar purposes did traditional
african religions share?

Africa is a free country to choose religions i.e. it’s a secular region.

Explanation:

Their constitution protects their right to choose own beliefs and religion. But in general the traditional African religions are based on oral traditions i.e. their basic beliefs and culture are passed on from elders to younger generations.

All the people following different religion rely on the elder generation for the culture and tradition. The major religious belief in African countries is Christianity, Islam, and Hinduism.

the answer would be in this answer. someone already asked the question.  

well it depends i think people around the world are coming around to gay marriage. but if you are talking abortion then wow, so much to talk about. such as men thinking they have the right to choose if women can, the fact there are health concerns if the women can't get one, and many more arguments to discuss. so i would definitely say abortion would be a much more interesting topic.
