To me, writing is the ultimate for of expression. For goodness sake, look at Stephen King! From his writings, can you imagine the dark, twisted corridors his mind has?? But if he tried to supress them, would he be where he is now?

Writing to me is the one place where you can let your imagination run wild without judgement. And fantasy is just that, fantasy. There is nothing saying that you have to act on your fantasies, but wouldn't it be great if your stories were inspiring to someone else who may come back and say "Hey! Thanks for the great idea!!"
