About people not wanting their records "out there": they already are. Anybody who wants to know anything about you can do so with a minimum amount of time, and if you're not using a shredder with great regularity, you're just making it easier for anyone to find out information on you.
As for your ancestors, there's a lot of information out there, but never as much as you'd like. There are THOUSANDS of different types of forms you can use to do genealogy, but I was only able to find one with the proper LDS terminology - after a lot of searching,
this form was found at
www.familysearch.org (the LDS site).
While I know that, at one time, I found ONE of my ancestors' marriages "sealed", I am unable to find it now. That's how "easy" it is to find.
While I use their records, I do NOT share my belief system with Mormons. Just read any one book by a former Mormon to understand why - and why I think this is all a tempest in a teapot. Anyone who even tries to call me an anti-Semite is seriously barking up the wrong tree, as I attended a Messianic Jewish congregation for years. Any real Christian prays for the peace of Jerusalem, and has a heart for His people.
If someone wants to get hopping mad about this, go ahead. You're not going to change anything. For heaven's sake, I've had more than one Mormon tell me with a straight face that they have traced their genealogy back to Jesus and Mary Magdalene and further! How can you even take someone like that seriously?!
ps - Sugarandspice - this may be one of the only threads on which we totally agree!
