What is the moral value of disgust?

The decision of OnlyFans and Instagram to ban the porn star Bonnie Blue, who engaged in sequential sex with more than a thousand men in 12 hours, indicates the strength of the backlash of disapproval to the stunt. The reaction of many people has been what the psychologist Jonathan Haidt calls 'moral bafflement', the idea that most of us instinctively condemn some behaviours without being able to say why they are wrong. Western morality says, “don’t hurt other people”, but Bonnie Blue arguably hurt nobody. This was understood to be safe sex between consenting adults (although the psychological or social impact is harder to determine). Others might form their judgments based on values within sacred texts, but religion is no longer the moral and cultural force it once was. How much attention should we pay to our knee-jerk sense of right and wrong when judging the actions of other people? Evolutionary psychologists describe how the emotion of disgust was a survival mechanism against the spread of disease. Thus, ritual purity, enforced by religious edict, was vital for the moral and spiritual life of our ancestors. But does disgust still carry moral weight in a modern, secular, and technologically advanced society, or is it merely an evolutionary hangover? Just because we think something is wrong, how do we know that it is? And do we have the right, as a society, to translate our instinctive disapproval into prohibition?
