There are a few things I notice that do bother me which I think authors should take into consideration when they choose to use curse words in their writing.
1. Just because it's common in spoken language doesn't mean it's necessary to use it in your writing.
- It being common in your circle of acquaintances doesn't mean it's common in that of your readers.
- There are people who use a swear word for just about every other word they speak. It doesn't demonstrate their intelligence, but rather the inability to get their point across. Be aware of this. Rather than throwing swear words everywhere, spoken by everyone, be sure to demonstrate the need for their use. They will make much more effective.
- Judicious use of a swear word will increase tension where you need it or give relief or release of it if they are not poured out on every page in every bit of dialog.
- Over use gives them much less impact.
- I assume you want as many readers as possible to buy and enjoy your books so they will buy more of your work in the future. Being inconsiderate to your readers by using the name of someone they love dearly can and does alienate Christian readers. Think of it this way. Think of someone you love deeply; a spouse, child, grandchild, etc. Now substitute that person's name for the use of Jesus, Jesus Christ, God where it is used as a curse word in your novels or novels that you read. Is this something that you like or want to read?
- Ask yourself, why didn't you use us Allah or Buddha as the swear word?
Is having your characters show their lack of communication skills as well as the inconsideration for readers who may be turned off by the use of swearing and their Lord's name being used as a curse word worth turning away readers? If it is, fine. Go for it. Just remember you've turned off many possible sales.
