Greetings, I reverted your edit because one cannot change the very definition of an article without some kind of discussion in the talk page, preferably accompanied with reliables sources supporting one's edit.
I'm sorry if my reverting seemed harsh but if you'll have to bring sources to back such a drastic change in the article,
no harm intended( i myself have reservations about using the term "pan-ethnicity" in the article), --Macarenses (talk) 14:36, 23 February 2011 (UTC)
