What is your opinion on profanity in novels? Is it necessary?

It all varies. Sometimes, it would be better if the character just cusses. It's just more believable the situation and the character. Other times, there's no need to do it. Like, a children's book shouldn't have profanity in it. But an adult book can have it. There's nothing against it. However, I'm not crazy about seeing F-- this, F--- that every other word in a book. And I have read books like that. Cussing just to cuss turns me off a story. If you have it because it's there/needed/believable/whatever, then fine. It works. But don't overdo it and don't do it just because you think it's cool.
