Mormons are baptizing dead Jews at holocaust sites. Apparently they have been doing this for quite some time.
They only baptize ancestors of current Mormon members, believing the baptisms will help reunite the families in the afterlife.
People in the Jewish community however find the practice highly offensive. Especially given the circumstances.
'Michel suggested that posthumous baptisms of Holocaust victims play into the hands of Holocaust deniers.
"They tell me, that my parents' Jewishness has not been altered but ... 100 years from now, how will they be able to guarantee that my mother and father of blessed memory who lived as Jews and were slaughtered by Hitler for no other reason than they were Jews, will someday not be identified as Mormon victims of the Holocaust?" Michel said Monday.'

Apparently they baptize Catholics and other faiths as well.
