Opinions on art and music are subjective. You tell me that your taste is better and criticize mine and I will treat you like something that just slithered out from under a rock.
Beliefs are not subjective. They are either true or false. If you criticise one of my beliefs, and do it respectfully, we can have an interesting debate. And, if you were persuasive, you might even change my mind. However, if your idea of debate is to ridicule my beliefs, then I'll treat you like something that just slithered out from under a rock. freespirit
Obviously you don't follow art or music criticism. There are real standards of what constitutes art and music that are educated opinions that are not subjective at all. Like beliefs these educated opinions can and do change as new forms get past the shock stage. But art and music still matter, and only the new forms that comply with the human goals of art and music to educate, stimulate, and move people.
Opinions about beliefs change more slowly as they are indoctrinated earlier and more intensively than opinions on art and music but change they do. Sometimes it takes generations to do so as beliefs occupy a more important area of the mind than esthetics. Social compliance with beliefs is frequently a matter of survival. Esthetics is more like manners; a group identifier rather than a coercive believe or die.
