Relativist claim: All forms of expression are healthyThe claims of relativism, however, deny this basic premise. Relativism holds that there is no inherent good or bad, right or wrong. Much like Bloom's initial belief, relativists think that morality is something denies the moral sensitivities we're born with. But no one can live this way in real life, and relativists contradict themselves even in the way they rear their own children. They set down rules, the biggest of which is "you shouldn't make other people feel bad." They worry about negative judgments affecting children's development. But any statement that tells a person what they should or shouldn't do is by definition a prescriptive statement. It's a prescription for behavior, and like a medicine that is prescribed to cure an illness, the statement is given with the belief that behaving a certain way will be better for those involved. However this doesn't make sense. Medicine works because basic human biology is the same for everyone. A doctor doesn't dispense medicine made for animals, but discoveries made that treat human illnesses in Europe or Asia will work effectively in the US, too.
To believe that morality is not similarly universal means that the same prescriptions will not work in different cultures or contexts. But if we are to "stop being so judgmental" because such actions are "bad" for people, then the relativist has underscored the fact that they believe there is a right and wrong way for people to act. In fact, I would venture to guess that even a relativist would have a problem with parents who never corrected any of their children's' naughty behavior, but allowed them to do whatever they wished. Our society would classify such parents as criminally negligent and they would be charged with a crime. That's because our society naturally recognizes that moral boundaries are essential in raising quality human beings and that to remove them is actually harmful, not beneficial.
