PITH is speachless.
I was raised in a household with traditional Christian values and I rarely indulge in any sort of profane language, but I have never had a problem with the cursing SK uses in his writing. People in the real world curse and SK's writing is a reflection of that. It does not change the way I speak, nor does it insult or offend me. I'm not trying to be a smart aleck or anything, but my best advice would be that if Stephen King's profanity offends you then you probably shouldn't be reading Stephen King books.
