Since the release of Matter of Choice, I've had some tell me, why not put this expletive here or that one there - it'll raise the intensity of the situation. I shrug those kind of comments off. Over the years, I've had arguments without the use of those words that were plenty heated. In fact, a scene isn't dictated by the words alone, but by the emotions, actions, and body language fueling the scene. No colorful language needed.
The only time I ever have struggles with writing without the use of swearing are for characters who would likely use them in real life. That can be a challenge - how to stay true to a characterization while censoring how they say things? But the truth is, it still can be done. Substituting words for others, and showing menacing gestures, etc. still achieves the same needed effect.
Do I stand firm on my decision of what words are used in my books. Absolutely.
What about you, my fellow clean authors? And what about you, our valued readers? I'd love to hear your thoughts on the subject.
