Well, I'll tell you why I am grossed out. I can't and won't speak for others. I am grossed out because frankly I don't want any possible disease you or somebody else might have had coursing through my body. In addition, just the thought of your human remains -- in any form getting on me in any way is, well, repulsive.
There are reasons for burials, outside the ceremony of it all. There are reasons people who are cremated are placed in urns and not simply dumped in a pile at Yankee Stadium or Disney World or all over the Empire State Building.
I mean, think about it. What do we know of SARS, AIDS, hepatitis, or any number of diseases out there? What do you know of herpes or any STD, for that matter? You mean to tell me only those who are 100% disease-free are allowed to do this? What if, God forbid, I die of full-blown AIDS, am cremated and my ashes are scattered on your front lawn because you don't see anything wrong with that. Is this still OK with you?
This is not something that's cool. This is something that is cool in theory. I get it. I understand the thought behind it all. Sure, I would love to spend eternity in the Tower of Terror -- who wouldn't?
But for the health of others -- for the safety or your child and others out there, I and whatever possible diseases I have, should be disposed of properly and kept where they can not infect or harm others in any way.
And the possiblity of THAT is what grosses me out.
