A federal appeals court began hearing arguments Thursday over whether a famous World Trade Center symbol can remain on display.
American Atheists Incorporated rallied in front of Manhattan Surpreme Court demanding the so-called "World Trade Center Cross" from the National September 11th Museum be removed.
The group says the cross-shaped steel beam found among the wreckage of the Twin Towers promotes Christianity and excludes other religions.
"We're looking for equality. We want fairness. We want equal representation for atheists. And when you have a religious symbol that is there simply because it is a religious symbol for Christians, you can't have that. So if you're going to start representing some religions, you have to represent all of them, including atheists, or you need to remove it," said American Atheists Managing Director Amanda Knief.
In a statement, the 9/11 Memorial President said the cross belongs at the 9/11 Memorial Museum and nowhere else.
A federal judge tossed out the group's lawsuit last year, but it appealed the decision.
