American Atheists: a bunch of jerks?

In July, the publicly-funded 9/11 Memorial Museum was sued by an atheist group to prevent the display of a cross made of WTC beams. The group American Atheists said on their website:

"This cross is set to be included in the official WTC memorial.  No other religions or philosophies will be honored.  It will just be a Christian icon, in the middle of OUR museum.  This will not happen without a fight.
...
We will pay for our own memorial of equal size inside the museum, or the museum will not include the cross.  Equality is an all-or-nothing deal."

The museum has since said that a Jewish star of David cut from the WTC rubble will also be on display.  American Atheists subsequently argued that since Muslims, Hindus, Buddhists, and atheists died on 9/11, they should all get displays in the museum--not just Jews and Christians.  Otherwise, the group argues, the cross should be removed.

What do you think?

Personally, I don't think it would be so terrible if the museum allowed several religions/philosophies to erect memorials.  But the whining coming from American Atheists is silly.  The group fails to recognize that the 9/11 cross is an historical artifact. It was used as a makeshift shrine by the laborers who were digging out bodies during the aftermath of the 9/11 attacks.  If the workers had memorialized a piece of rubble resembling an atom--which is the symbol of American Atheists--I expect that would be displayed in the museum, too.  But history does not respect American Atheists' definition of "equality", and our museums would surely be impoverished if exhibits of religious significance were an "all-or-nothing deal".  (Imagine trying to apply the logic of American Atheists to a memorial museum of Reverend Martin Luther King, Jr.)

I'm relieved that other atheists agree this 9/11 cross suit is much ado about nothing.  I have never liked this group, American Atheists.  They try to remove roadside crosses--you know, those harmless memorials for people killed in car accidents.  Frankly, they act like jerks.  Pouncing on every opportunity to claim offense, and throwing tantrums over trifles, is just as tiresome when it comes from atheist groups as when it comes from Christian groups.
