Final answer:
When a friend says they believe wearing fur or leather is morally wrong, they are sharing a personal moral standpoint, which is influenced by emotions, societal norms, and individual ethical beliefs.
Step-by-step explanation:
When a friend says, "I feel that it's morally wrong to wear fur or leather", he is expressing a personal moral standpoint. This standpoint comes from one's internal value system and ethical beliefs, which are influenced by a mixture of instinctual, societal, and rational factors. According to moral philosophies such as Emotivism, this expression is a reflection of one's emotional response to an action or practice, which does not necessarily entail a truth claim but instead communicates feelings.
The complexity of moral judgments is recognized by various philosophical arguments, from David Hume's sentiment-based ethics to the social constructs discussed by Thane Doss, pointing out that ethics and morality are in many ways products of the society in which we live.
