A group of atheists is up in arms over the display of a cross at the 9/11 Memorial and Museum. The World Trade Center memorial, which is intended to serve as a reminder of the tragic terror attack that occurred nearly 10 years ago, is scheduled to open on the event’s 10th anniversary.

When the Twin Towers collapsed on September 11, 2001, two beams perfectly formed the cross, which many view as both symbolic and iconic. It is this object — a steel cross — that is perfect fodder for atheists and non-believers who do not wish to see any religious items included in the memorial.
