Why is it that in Israel, its considered unenlightened to want revenge for the murder of innocents? The media paints any group of people that go to a terror attack site, and yell for "revenge", as a bunch of loonies (and Kach). While within Judaism, there is a mitzva of not taking revenge: לא תיקום ולא תיטור את בני עמך, this does not apply against our enemies, and Judaism definitly does not believe in the Christian concept of "turning the other cheek."
Across the blogsosphere, GodolHador and DovBear have made reference to the Biblical Revenge Song of the prophet Samson. (music by Dov Shurin) -- mostly with disdain. Dov Shurin's song is so iconic, that even the "Otiyot" children's magazine related to it. Otiyot is very mainstream, so I assume the idea is pretty much accepted.
