A Liturgical Quandry

Those of you who've used certain prayerbooks have encountered the version of Kaddish with the names of concentration camps interspersed between each of the words. It's absolutely horrid, in terms of the meaning of the text of Kaddish, which praises G-d, and is not actually a mournful text.
