Two wrongs don't make a right, but I think people should be able to create fantasies on whatever they want. Might not stop someone suing for damages though. Photoshopping jizz on someone isnt nice either but guess you can't stop people from doing it.
I wonder if Kim Davis could sue the author of the novella using her as a character. I'm doubtful. On the other hand, the U.S. does have a reputation for lawsuits over everything. Who knows.
