I of course reject mormonism (and chr*stianity as a whole), but I simply do not understand why these mistaken people engaging in this peculiar rite of theirs does any harm to Jewish souls who have already passed on and been judged by HaShem based on their loyalty to Torah. I'm certain many sincere chr*stians pray for the conversion of the Jews (G-d forbid!), but since this is contrary to G-d's will, I do not believe He is going to grant this request. I assume He looks on the good intentions of these chr*stians and will answer their prayers in some more appropriate way. But why make a fuss about the fact that some people are praying or engaging in these rituals in which no Jew is involved and which cannot possibly cause any religious defections???
However, the mormons are historically very pro-Israel, and it seems that at this time of universal isolation of Jews and Israel when chr*stian Zionists and philo-Semites are their only defenders, there is an awful lot of noise emanating from certain Jewish circles doing all they can to offend these people. The whole thing seems fishy to me. I also note that none of these troublings of the waters ever involves calls for the gentiles to eschew false religions and come to HaShem as Noachides but always seems to advance the diabolically stupid position that religion is purely subjective, no one of them being objectively true. (What a blasphemy that this very idea is often trumpeted as "the meaning of Chanukkah!")
Please note that I am not standing up for a false religion or its rituals, but only remarking that this particular practice (mormon baptisms for the dead) doesn't actually involve any Jews and cannot possibly cause deceased Jews to become mormons in the Garden of Eden (how riduculous!). At any rate, any Jew offended enough at this private, non-Jewish ritual should be offended enough to want to make Noachides of the erring people involved.
If I am offline here and deserve a rebuke, I will submit myself to Alouette.
However, I belong to several geneaological groups whose members have travelled individually and in groups to the genealogy center in Salt Lake City (which I have not personally visited). Some people get very incensed over this whole posthumus conversion thing, even after making extensive use of the archives and the database which the Mormons have worked so hard to provide.
I say to them, get over it, it's not harming your ancestors.
BTW a cousin of mine converted to the LDS church (while still alive) after marrying a member. So I'm pretty sure that all my ancestors have been "baptized."
What do you think about Jesus, and His claim?
