All right, let's test that. We'll try a few beliefs.
In parts of southern and eastern Africa, people who are albino are frequently hunted for their body parts, which are believed to be able to magically produce riches, power, success or sexual conquest when use in magic/rituals. Do you believe this, or not? If the answer is not, can you give me an actual reason for not believing it?
In parts of China, Vietnam and other areas of Asia, it is believed that bear bile is a useful medicine, used for curing liver, heart and other ailments. Thousands of bears are killed, or even worse, kept cruelly in small cages in which they can't even turn around, and their bile is surgically extracted, often clumsily, leading to great distress and death. If you don't believe in harvesting bear bile for health reasons, can you provide an actual reason for not believing?
