In my opinion, you don't want to blatantly offend anyone, but at the same time. Because I personally believe people have gotten WAY too uptight and PC, I make a point to do things like using names like those on my stones. Most of the children don't notice, and most of the parents get a laugh. The way I see it, unless you are being blatantly rude,,,, "F' em if they can't take a joke.
