I think the OP has been a bit too defensive, and I think others on the thread -- particularly ivywhore -- have been a bit too offensive. Everyone chill out.
Let's get back on track, shall we? The question raised by OP is a good one, if we simply extrapolate it out more broadly at first: Are there groups who deserve URM status, who do not currently receive it? And if so, are Jews among these groups?
I think the answer to the first question is very probably "yes." But some of the groups mentioned on this thread are not among the groups that are not receiving URM status, but deserving of it. Palestinians (or Arabs), for example, are undoubtedly receiving URM status if they draw attention to their ethnicity -- I would think this group would be a hot commodity among law school admissions boards. And "eskimos" (I believe the better label is "Inuits") are undoubtedly counted as Native Americans, and thus receive URM status.
But what about other groups? What about Greeks? What about the Irish? What about Italians? What about Buddhists? What about Mormons? What about transvestites and transexuals?
And yes, what about the Jews?
I think the question about the Jews has been asked and answered. The Jews, while undeniably persecuted throughout history, and while undeniably a minority group, have long enjoyed over-representation in the legal, medical, and political professions (not as politicians, but behind the scenes as advisors, staff and cabinet members, etc.), as well as in the entertainment industry. Also, in America -- perhaps due to this over-representation and professional success, Jews have in many respects been assimilated into "whiteness." (There are books on this, for the OP or anyone else who is interested.)
As for the other groups, I would say they fall into one of three categories: a) they are not groups we "care" about politically or culturally enough to single them out for special attention (e.g., the Greeks); b) they, like the Jews, enjoy a certain amount of over-representation in the legal profession (e.g., the Mormons); or c) they are receiving, or would very likely receive, some special consideration as URMs if their identity was made known in the application (e.g., transexuals).
All this being said, it should also be noted that URM status is not the only way to acquire some special consideration. If you've suffered hardship or obstacles to your professional development, these can be noted and do receive consideration, regardless of official URM status. Poverty, first-generation college grad, and other things like this fall under this umbrella.
Personally, I too believe that economic status is a much more important consideration than race or ethnicity, when considering "diversity" and representation.
