@Thomas,
I never ran across those articles, or if I did forgot them soon enough - I just on the face of it don't mind the steel beam crucifix; it's strong, and now that I see the history you refer to (I knew it was from the site, but not all your details), mind it less, especially if it could somehow represent all of our sorrow, whatever our faith or lack of it.
But, I do see Set's point re what it can set off, and that is additive to what bothers me if all other possible religions (or not religions) of those who died have to be represented, bringing me back to aesthetics.
That is, back to why I liked the vietnam memorial solution of Maya Lin.
I need, as I said, to go see what is going on with the memorial site plans. In the case of Maya Lin's work, the memorial itself is the symbol for all, the names of the dead carved in granite that is, as a shape, buried in part in a formed earth berm.
I don't know that that is what is going on in the WTC memorial plan since I don't remember seeing the plans, at least lately.
Wonder what Maya Lin would have done. I remember reading about her comments back not that long after 9/11. Mostly they were about the street planning around the site, to the extent I remember. And I vaguely remember that she didn't want to be involved, busy doing other work.
I also figure that wacko lulus of many sorts will show up, no matter what the decision.
