A slightly more balanced account:

The practice has not been without controversy, however. In the mid-1990s, there was a backlash when it was uncovered that the names of about 380,000 Jewish Holocaust victims had been submitted for posthumous baptism by what church historian Marlin Jensen calls "well-intentioned, sometimes slightly overzealous members." In 1995, the church agreed to remove the names of all Holocaust victims and survivors from its archives and to stop baptizing Jews unless they were direct ancestors of a Mormon or unless they had the permission of all the person's living relatives. However, Jewish names have periodically been discovered since the 1995 agreement, including that of Holocaust survivor and Jewish human rights activist Simon Wiesenthal, which was found and removed in 2006. Catholics and members of other faiths have also been upset at the practice.
