Bonjour,
With the use of art, you can show the world how slavery is and you can make people think about it. Nobody can cancel art because it will go against our rights in it's illegal. I would say that art can be the window of the world that we choose to show and sometimes the visual art are more effective than the audio or written arts.
J'espère que ça t'a été utile! ;)
bonne journée
