Advocates of a theory known as moral relativism subscribe to the notion that moral virtues are right or wrong only within the context of a certain standpoint (e.g., cultural community). In other words, what is morally acceptable in one culture may be taboo in another. They further contend that no moral virtue can objectively be proven right or wrong Critics of moral relativism point to historical atrocities such as infanticide, slavery, or genocide as counter arguments, noting the difficulty in accepting these actions simply through cultural lenses.
