Sounds like you're arguing that Dr.Hyde's post should not be read as a causual blasphemy. I don't think that's tenable.

I'm somewhat puzzled that sexual references are used for swearing, but they are used that way. I don't find them offensive, but some do. If no one found them offensive, they wouldn't be much good for swearing, or for humor. Swearing would have to move on to another topic.

The power comes from crossing some boundry of courtesy or a suggestion of crossing that bound, as in "Good Gravy!". Once something offends no one, and doesn't even make a weak reference to saying something offensive, it doesn't make much of a swear.

"Breakfast!, that's hideous!"

doesn't quite do it, except as a parody.
