IDoR a link to the original.
To remove any ambiguity whatsoever, the point of the article was simply this:
No topic should be off limits. Nothing should be exempt from being story fodder. Whether rape, murder, torture, mutilation, cannibalism, racism or any other nasty thing anyone can think of. Artists must be free to explore without being censored, controlled or limited. The mere existence of something nasty in a story, game or piece of art is not sufficient reason for the art – or the artist – to be pilloried. Nor should we only allow people we consider (subjectively) skilled or politically acceptable to tackle difficult subjects.
TL;DR – Censorship is bad, offence, upset or discomfort isn’t a good enough reason to prevent something being made.
If you still object to that, stated as plainly and simply as that, we’re going to have a problem.
