<i>Milk and semen are not symbolic to Catholics. Neither is urine.</i><p>the symbolism may be in their exclusion and denial from the catholic cult.  in many of its strains catholicism is so exalted you&#x27;re only supposed to have an eternal soul, your body is filthy.<p>which brings us back to <i>modern art is just juvenile satire</i>.  my take on this is it&#x27;s necessary (and won&#x27;t stop being necessary as long as there are new people coming to this world) but in now way should be the only or the most cherished form of art.
