Moral and physical disgust are registered by the same part of the brain and give much the same emotions. This is why propaganda often seeks to link olfactory (smell) and visual forms of disgust with the group they are trying to raise prejudice and cold indifference toward. Thus "yucky" can be as tame as a dislike of a flavour to an emotion that can alter history.
