Browsing the main page I came across a recently updated story tagged as incest between cousins.
That got me thinking. Over here in Germany, marriage is permitted between first cousins, so it wouldn't fit the legal definition of incest.
That leads to the next question: What is the guideline for selecting tags? If I write a story that takes place in Europe, where such a relationship is not unlawful, do I still need to apply the tag?
There are even more serious considerations coming from that. For instance the age of consent varies from country to country. For instance in most European countries sexual contact between an 18 year old and a 14 year old would be perfectly legal as long as there is no abuse or coercion involved, while in other countries it is considered statutory rape.
So what exactly is the 'guiding light' here? Do we all have to consult American law or do we go by what the law is where the story takes place?
