Well, in the definition of the term, ethnic Moldovans are not associated with Romania (I am not saying that the definition is right, just that we have to deal with it, especially on disambig pages). My main point about Sîrbu was that, since he is a Moldovan citizen, and Moldovan-Romanian through this, there is no reason to wonder whether he is also a Moldovan by ethnicity; the only exception would be if Sîrbu is also, according to his own definition, an ethnic Moldovan - but this would still wouldn't matter for the main topic. The real question is "Are there any Moldovan ethnics who are Romanian citizens without being (or having been) Moldovan citizens?". The answer, as of yet, is "No", as we can all agree.
