Les,
what you are missing is that you won`t be able to find a country named "Ethnicia" on the globe.

Since it is not directed to any specific ethnicity (everyone is one somewhere) who can claim that it is directed towards him?

If this is offensive every joke about Irish, Polish, German, English, French, male, female, senior, junior, gay, straight people, lawyers, doctors, politicians musicians - in other words: about everybody would be offensive.

Admittedly artificial-persons-designed-to-satisfy-the-carnal-needs- of-people-who-are-attractivity-or-boldnessly-challenged might find the term "fuckdoll" offensive...
