All art promotes or opposes particular political values. All art is
propoganda. Most of us are simply unaware that our own prejudices and
unconcious assumptions are broadcast through our work. We all form our
views and beliefs based on the culture to which we belong. From
childhood on we imitate what we observe. The artist has as much
responsibility to conciously choose the messages they convey and
consider the potential impacts of their works on society as a
housebuilder has to consider the strength of their building materials.
If a house is built carelessly it may fall down on it's occupants, and
if an artwork is made carelessly it may create a net harm to society.
At the least, the social responsibility of an artist is equal to anyone
making anything. Artists are not exempt from ethics nor are they
society's sole guardians. Every action has an effect, no matter how
subtle.
