That's very true. But I don't see it as the same. The ancient Egyptians probably didn't sell little pyramids next to the sphinx. 9/11 is still engraved into our collective consciousness. And for some, it is still very much a open wound. I feel this museum is salt being rubbed into that wound. To me, it doesn't matter if the section is closed of or not. I feel that this site should be treated like that of the Tomb of the Unknowns. With honor and respect. Not a tourist attraction sideshow.
I'm just pointing out the hypocrisy of treating some remains as sacred things that can't be commercialized and others as just fine to commercialize. Everyone loves to get indignant, but when it's someone they don't know suddenly it's just different. It's a silly response.
The only real question that I have is one that isn't addressed by any of the media coverage or articles cited (isn't that always the way, the real information is left off altogether in favor of stuff that doesn't matter). Who owns the remains, who owns the museum, is it the same entity, if not what is the contract? If the answer is that the state owns the remains (since they are unidentified) and that a private entity owns the museum and that the state has contracted the remains to the private entity, one has to wonder why our government made that decision. The problem then is addressed not by compelling the private entity to do or not do something, but by figuring out why the state chose to do this and taking action to undo it.
If the private museum owns the remains, that's just weird. How did that happen?
If the state is somehow running, and yet not funding (also weird but not unheard of), the museum, then what the museum is choosing to do and how it portrays itself is directly accountable to the public.
If this were me, and it was my relative who was lost during the attack and whose remains were among the 8000 that could not be identified, I have to say I'd be fine with it.
There is nothing, by the way, preventing additional memorials for any individual lost in 9/11 from appearing anywhere on the planet. If it were my wife who died in the attacks (I just picked the person most likely to spark a strong emotional response from me over remains), I would create a separate memorial. It would not be enough for me to have her lumped in with a thousand other people in one big memorial.
