Honestly, coming from one of those cultures, the belief in witchcraft and sorcery holds to many people back when it comes to addressing actual ills like people dying from undiagnosed diseases, mental health conditions, behavioral disorders (one of my friends here sent his kid back to his home country to get traditionally "treated" for autism). My people believe that witches fly in sardine cans only during the night (I'm ******* serious); some still believe that folks can turn into animals. They believe that planting a hatchet in the ground will stop the rain, and yes, I tried it when I was younger because I didn't know better and the people I grew up with believed it to be true.
Everything good that happens is the work of God, and everything bad is a curse, death included. Died of lung/liver cancer? "God (or their enemies) cursed them with cigarettes/alcoholism." The funny thing is, the exception to this rule is always professional success: if you're doing better than the average, "you sold somebody's soul", "you're in a gay cult" (the most distributed newspapers routinely publish "stories" of gay secret societies and their alleged members), "you're selling drugs/sex/organs overseas," etc...
There was time when most people believed the the Earth was the center of the universe and everything revolved around it. How did that one turn out?
It's not enough for people to assert that something is true, especially when they themselves are not in position to offer proof. Nobody ever demonstrated to me how a sardine can could fly, and every time, it was because the people telling me about this magic admitted they weren't initiated in those arts and didn't know anyone who was. But "trust me bro," right?
