Example: Ilya Sheyman. While he's never specified what his parents' views are, he's a great example of a very young, Generation Y member of the eastern European Jewish community who is also extremely progressive.
Oh, it's the common lament of middle-aged Russian Jewish parents: their kids do not share their views. Actually, it's more like their kids dread their parents ever opening their mouths to talk politics in public. Just imagine, being a run-off-the-mill good Jewish kid, who's gone to Harvard or Berkeley, who volunteers for good causes etc., and whose Dad has Reagan's portrait onf the front page of his family photo album and is convinced that Obama is a Kenyan-born Muslim who wants to bomb Israel. The worst thing is, the same Dad, half the time, is equally vocal about Putin being the best thing that ever happened to Russia (unless, of course, he is determined that those Russians who stayed are all subhuman and Moscow should be nuked).
