What are you talking about? Those are some of the best paintings ever created. Anyone trying to tell you different is probably a fascist or communist. Both authoritarian and hate-filled ideologies that have no place in modern or future societies.
Hitler probably helped an old lady cross the street once too. Terrible people or those supporting authoritarian ideologies can still do nice things. They pet dogs and eat ice cream too.
It ’s an actual position. These kinds of ideologies hate “the good life” and consider such paintings either decadent (fascists) or supportive of the bourgeoisie (communists).
