When I write I'll sometimes say things which are somewhat controversial - not because I'm seeking out controversy for its own sake, but if I don't have anything to say which is different, why am I bothering to write stuff down in the first place?
I am never going to write about dogs again. You can write about Islam, you can write about sexuality, but no, not dogs.
When you start writing things to try to persuade someone who's not already part of your guild or your profession that something is interesting, it forces you to ask yourself, "Well, why is this interesting?"
