Oh, so if they'd put up a "rainbow" or a hammer-and-sickle to celebrate their "solidarity", then it'd still be there.
Not a lauging matter. The a--holes who designed the memorial already rejected the suggestion by the majority of families and the FDNY, and the PAPD, and the NYPD that the names of the deceased be grouped by where they worked. The designers felt that it was important to deemphasize the individual in favor of highlighting the randomness of the destruction, whatever that means.
