Expressing it in a will should take care of that

Donate your body to science?

Convert before you die.

Have a 'hitman' clause in your will to dispatch any prick who comes near your grave with a vile of holy water.

That's a good question. The thing to remember is that everyday a large number of people pray for you and everyone else. A prayer/baptism said just for you is not going to change anything. You will be fine in regards to that.

You can send a letter addressed to the LDS First Presidency stating explicitly that you do not want to be baptized after your death to: The Church of Jesus Christ of Latter-day Saints Administration Building 47 E. South Temple St. Salt Lake City, UT 84150 U.S.A. The current First Presidency consists of: Thomas S. Monson Henry B. Eyring and Dieter F. Uchtdorf However, there's no guarantee that you still won't be baptized by proxy after your death as statements, regarding the baptizing of Holocaust Victims, by LDS Church members indicate: "In 1995, Mormons and Jews inked an agreement to limit the circumstances that allow for the proxy baptisms of Holocaust victims. Ending the practice outright was not part of the agreement and would essentially be asking Mormons to alter their beliefs, church Elder Lance B. Wickman said Monday in an interview with reporters in Salt Lake City. We don't think any faith group has the right to ask another to change its doctrines," Wickman said. "If our work for the dead is properly understood ... it should not be a source of friction to anyone. It's merely a freewill offering." http://www.foxnews.com/story/0,2933,449727,00.html But not to worry, as one commentator noted: "For the benefit of my friends and family, I would appreciate it if the Mormons would leave it alone, but other than that, I don't really care what happens to my body after I die. They can baptize me in the deepest ocean for all I care and it will not change my beliefs. As far as I am concerned, what one believes is more important. I don't recognize their baptism as being valid now, I don't believe that God recognizes their baptism, so why should it matter to me what they do after I die?" http://askville.amazon.com/SimilarQuestions.do?req=mormons+Anti+Thinking+religion

I doubt that you can, but why is that a problem?

Dround yourself... I do not recommend it though because being baptized is a much better thing.

You can't. You have no control of anything that happens after you're dead--you're just dead. Whatever you request before you die may or may not happen no matter how well your will is drafted.

Why would you care?

I have never heard of such a thing. What does that do?

Why care given it's just another fairy tale amongst the others.

Basically, you would have to make it known to any family members who might be LDS that you do not want that ordinance performed in your behalf. However, I can't guaranty that that would prevent it. Such a desire may become forgotten by future generations and they may perform the ordinance anyway. However, I would have to ask, like some others have, why does it really matter to you? I assume that you probably don't believe that such an ordinance is valid. If it is not a valid ordinance, then it is meaningless to perform it. That being the case, someone performing the ordinance on your behalf would not have any affect on your soul. So, it is rather pointless to worry about it. You might also consider the fact that the ordinance is not intended as a show of disrespect for you. Quite the opposite is the case. It is a show of love and concern. Someone it taking time out of their life to perform an ordinance that they hope will help you to gain salvation. If we are right about the nature of the ordinance, you will still be able to reject it if you wish to do so. So, no one is forcing anything on by performing. They are just providing an opportunity. It is still entirely up to you what you do with it.

Have a pentagram on your tombstone.

Hi, I am baptist and we do not do this but I have a question for you, why do you care? I don't care because for me this is a nothing thing. For me you must decide if you will go to hell by doing nothing or if you will choose eternal life by accepting Christ. So, either way, it does not matter to me so please share with me why it matters to you.

If I were the religious type, I really can't say how that would make any measure of sense. I think it's just to appease the relatives of the deceased.

You cannot. The mormons continued to baptise dead jews even after they promised to stop. Like every other holder of the "truth" they do not feel beholden to the laws of man.

Write out a request on not being baptized that after death you do not wish to be baptized my any church or religion. Get it notarized, make it down to a wallet size card to fit in your wallet. They will find it.

When you die have yourself quartered & buried in 4 secret locations all around the world. That'd stump em!
