Ethical relativism cannot make a claim to tolerance being universally good if all values are culture-relative.

TRUE

Ethical relativism proposes that morality depends on the norms of one's culture. Because cultures are different, certain actions may be right in one society and wrong in another one. Following this analysis, ethical relativism cannot definitely say that tolerance, or the acceptance of differences, is morally right. Because ironically, other cultures may view tolerance as immoral and the concept of ethical relativism should respect that.

Answer:The above statement is TRUE. Explanation:

Ethical relativism is the philosophy that regards that morality is contingent on the standards of one's culture. That is, whether an activity is appropriate or dissipated depends on the moral standards of the community in which it is exercised. The identical operation may be virtuously rational in one community but be modestly illegal in different.
