de gustibus non est disputandum

Uncertain; likely of non-classical origin. An alternative, more recent form de gustibus et coloribus non est disputandum (“there’s no arguing about tastes and colors”) originated in French literature in the early 19th century.

     […] moral debates cannot be ended with one's taste, nor with the adage: "there's no accounting for taste", which is absurd for morals.
