A few months ago Stagg and I had a big fight. Three hours. At three hours we just had to say, okay, we're not going to find agreement or peace with this one. We better just let it go and walk away. We even had to google during our fight for answers:what is the history of the symbols etc etc.
We were arguing over whether it should matter what the Red Cross/Red Crescent should look like when it is on a mission to help save lives. In a nutshell, I said the emblem shouldn't have religious history, and Stagg said it wasn't a religious symbol, and it shouldn't matter if it is a religious icon.
On January 14, 2007, the Geneva conventions listed the Red Chrystal as a third emblem for the health organization. Whew, peace in the homefront!
