This episode is primarily focussed on ethical issues arising from freedom of speech. It questions whether (and in what contexts) speech should be restricted or censored, and whether there are some forms of speech (and expression more generally) which should not be protected. The episode considers the question of whether pornography should be considered as free expression, and briefly explores debates related to censorship of video games and other media. It raises the ethical dilemma of whether we should protect the freedom of people to express themselves, or protect people from the harm which can be caused by others’ speech.
