Couple of points I can't resist making, of course!
Firstly, (no suprise) I think mostly along the lines of jlN;
[say, we should start a thread where we go through all our opinions on everything, until we find something we disagree on, and......
]
Meanwhile, back at the subject;
Secondly, and least important, I take offense to the term "atheist" as it is a term invented by those for whom life is run by supernatural "controllers", which obviate people's taking control of their lives, and being responsible for themselves, and those around them, in the here and now. This does NOT include the many people who use religion as a force for good in the world; only those who use it as an excuse.
I don't think it is necessary for a thinking person to label themself for the benifit of those who do not have the energy to decide for themselves whether they agree, or disagree.
And thirdly (some couple, eh?); feeling strongly moved and upset by death is not a phenomenon of subsurface spiritual forces, it is simply our humanity manifesting itself, and not feeling this way indicates serious damage, that may not be reversable.
Why do deeply religious people grieve for their lost loved ones, rather than rejoice at their "luck" at having "passed on", it is related not to their religious beliefs, but to their humanity, that they care, and hurt.
