not looking to start an argument here just stating my opinion.......were all the people that were killed during 9/11 of christian faith......in all likelyhood i would say not......im sure there were people of jewish faith, pagan, buddhist, satanism, jehovahs witnesses, wiccan, atheists etc.......i may have read that wrong but i believe it was said that they made the cross of steel beams from the site and had been place in a church to now be placed in the museum........in a case like this i feel it appropriate to incude all faiths/beliefs or none at all.
