@rooeytoo Overall I pretty much agree with you that people are forotten in a generation or two. I also think if we keep burying everyone, all the land is going to be full of graves. Some countries have gone to cremation in a big way because land is more scarce. Arlington is a special place I guess, for veterans, different than your average cemetary. I think a symbol of faith is just tradition. I guess since faith many time speaks of where you go when you die. Also, because religion is many times one of the big identifyers for a person. American, Christian, mother, wife, sister, etc.
I have no idea what I want when I die. I guess I should figure it out so I can put my request in. Buried, cremated, where buried, where to lay my ashes, I have no idea. If my husband died I would want to have him near me somehow, or able to visit. Could be ashes in an urn in my house, or a grave, not sure. I think I would let his parents choose while they are alive if he has not specified. I have no idea about a religious marker for him though. He was raised Catholic, converted to judaism, but it not reigious, but he is a theist. Probably I would not worry about a religious symbol on it for him, but then again his parents might care?
