Prayer for those who are dead (for non-LDS, anyway) is not to convert. Praying for souls is just that: praying for souls. It doesn't attempt to convert Jews to Christians and it doesn't pretend to. It doesn't say to Jews that died for being Jewish that they'd have been better off LDS members.
Does praying for people in Purgatory insult the memories of Jews who died in the Holocaust? Not in any way I can think of.
I've never heard a single Jew complain about it. But plenty have complained specifically, and loudly about proxy baptism. Why do you think that is?
People of the Jewish faith have asked many times that the practice stop, yet it continues to this day. See: http://www.jewishaz.com/jewishnews/040227/mormons.shtml
And what indulgences have to do with anything is beyond me, unless you need to change the subject away from the one at hand.
Excuse me LDS don't convert, the Holy Ghost does that!
The world convert the world to the world various religions but only the Only Holy Ghost can bring a soul to Christ!
No mortal can do that, I was witness too by the power of the Holy Ghost just me and the Spirit of the Lord.
Than I investigated the Church.
Prior to that I never met a missionary. You are misguided in your process! Thinking in they ways of the telestial world isn't going to elevate your thoughts and it seems very few every elevate their thoughts to the ways of the Lord.
Either way, isn't it about trying to get that person's soul into heaven?

I don't think so. It reflects on those doing the praying rather than on those who have passed on. I would imagine some Jews might be upset by it, but that doesn't impact their memory of their loved one.

Are you saying the Catholic Church never sold indulgences to people so that punishment for sins of those who have passed on could be remitted (in full or in part)? Come on - we both know that occurred.
How would sale of indulgences be different from praying for someone or getting baptized for someone who has passed on thinking that act can somehow change the 'destiny' of that individual?
Like I said, it reflects on the person undertaking the action, not on the person who has passed on.
