Any form of art should be a free expression of creativity on other hand we also talk social responsibility of an artist.
We can not rule out political content in Kundera’s work, James bond movies…
We can not rule out debate that was generated by the frontal nudity of Sekhar Kapur’s movie Pholan Devi.
Same is the case with discussion of uses of metaphors, absurdism or even the definition of things like postmodernism.
The consensus: Self censorship or to have a self defined line of control while expressing themselves.
But this vague line is different for each and every individual, so the argument continues.
