For a MOD thread, what specifically is offensive language?

You know there are some nuns out there who think "damn" or "hell" is the worst thing there is.

You can't do it. You can't draw the line where YOU think the line should be. Calling someone a used tampon is not swearing. True, it might offend someone, but calling someone a roll of toilet paper might also.

Again, this can't work, because it is still imposing someone's definition of the world according to someone.
