Challenge of Cultural Relativism

On page three of James Rachel’s the Challenge of Cultural Relativism, he lists six claims made by cultural relativists to support the concept of cultural relativism. Choose the claim you think is the strongest and explain why you think it is the strongest claim AND then choose the one you think is the weakest claim. So, to be extra clear, you will be unpacking two different claims in this discussion board. You cannot choose #1 for either because it is simply a fact.
