I don't think art is propaganda it should be something that liberates the soul provokes the imagination and encourages people to go further. It celebrates humanity instead of manipulating it.
Anger if not restrained is frequently more hurtful to us than the injury that provokes it.
No man has the right to dictate what other men should perceive create or produce but all should be encouraged to reveal themselves their perceptions and emotions and to build confidence in the creative spirit.
