"I have rejected an old rule by which Serbs from Serbia used to be described as Serbians but Serbs from Bosnia or the old Austro-Hungrarian territories were distinguished by calling them Serbs. Today I believe that such a distinction is confusing, especially since few people know that it ever existed. Another premise which I reject: some believe that citizens of Serbia, be they ethnic Serbs or not, should all be described as Serbian. I do not think that this adds to clarity because it would clearly absurd to describe a Kosvovo Albanian as a Serbian. Likewise, some insist that when writing about Albanians in Kosovo one should always write about ethnic Albanians to distinguish them from Albanians from Albania. I think that Kosovo Albania is often a perfectly suitable alternative and there seems to be no reason for dogmatism over which term to use."
Note that I do no entirely agree with Judah (2000). However, I (and others) think you can see the issue.
Who in the hell is Tim Judah to "reject" how people have defined themselves for centuries? What a moron! Tells you a lot about his abilities (or lack thereof) as a historian and author!
