The facts about the african witch hunts just show that regardless of what the true teachings of a religion is (i.e. Islam, Christianity, Judaism, etc), its individual followers would still find a way to distort it in their own sick way, resulting in the horrible acts of crimes we have been witnessing: terrorism, ethnic cleansing, genocides, witch hunts, etc.
No religion teaches those. Although I am not a scholar, I will challenge anyone saying that the religions teach such.
Oddly enough, history has shown us that not practicing religion also goes along with people being asshats. Instead of doing it in the name of "God", atrocities are committed in the name of "Reason", "the Revolution", "the People", etc.
