I agree with you in spirit. The problem is that you actually absolutely *can* make disgust the basis of your morality system– and doing so will powerfully fuck up your mental health, your perception of reality, and your relationship with everyone around you.

“You cannot make disgust the basis of your morality system” is a judgement about what I think is or isn’t a good idea for you and for the world.

“"I don’t think anyone should be allowed to read or write this because it is disgusting to me” is authoritarian.“ is an actual and indisputable fact.
