Furthermore, Blasphemous Art could work as a shock therapy to get theists into thinking and questioning their religion.
Blasphemy is questioning something considered holy and not allowed to be questioned in their belief, e.g. a god, the Prophet Muhammad, the “Virgin” Mary. Blasphemy explicitly shows something that is even forbidden to be thought of for a beliefer. So blasphemy can show the “un-thinkable” and thus start a process of deconstruction of faith.
For many theists this may start subconciously as their conscious thoughts are trained by religious upbringing to reject the blaphemy. But subconscious needs can be more open to blasphemous content. Take for instance sexuality that is restricted and supressed in the Abrahamic religions. Showing the Prophet Muhammad in a homoerotic situation is clearly blasphemous for a Muslim. But if this Muslim is a latent homosexual and supresses his sexual desires, such blasphemous art could awaken something. He could start to realise that deep inside he likes what he has accidentially watched. In this way a process of exploring the cognitive dissonance of being a homosexual and a devout Muslim could start, that finally leads to a self-liberation from religion.
Blasphemous Art could be a nudge for religious people to free themselves, something I consider to be very positive.
