Final answer:
In a public political discussion, arguments should not be made for a moral position because morality is subjective and varies between individuals and communities. This belief is rooted in moral relativism and the recognition that there are no universally objective justifications for moral beliefs.
Step-by-step explanation:
In a public political discussion, there are arguments that one should not argue for a moral position. This position is often based on the belief that moral arguments should be based on individual or community values, rather than being imposed on others.
It is argued that moral relativism, which recognizes that morality is relative to an individual or community, makes it difficult to determine what is truly good or bad. Additionally, proponents of moral realism argue for an objective concept of morality, suggesting that there are certain moral facts that are objectively true.
