if you say a puppy is cute and a snake is ugly, you have said exactly NOTHING about either.
you have only said something about yourself.
sexual intercourse or oral sex are not the definition of porn. describing the photo on the left as porn only says something about YOU, not the photo.
same goes for calling one photo ugly and one photo beauty. the photos are what they are. NO MORE and NO LESS.
any relative subjective value judgements placed on either of them say NOTHING about the photos.
they only reveal something about the person MAKING subjective value judgements, and proclaiming them to be "definitions."
meditate on that.
