Not being from USA I didn't know they were fighting. I will have to remember this.. What does each side say?
As an American, I never heard of such a discussion so the reason of discussion would be also unknown to me, but I can guess, some people like to make a big deal out of everything & connect every unrelated spot to another unrelated one. Besides, to me it wouldn't really be matter. The discussion is waste of time, cause nothing will change in aspect of our founding fathers & what they've done. Those beliefs are personal beliefs & it varies for each, those Atheist & Christians are totally wasting their lives over such a useless topic, because regardless which side the founding fathers been.
The first of commitment of the United States of America is "Freedom of belief & freedom of choice" so the result of their discussion wouldn't make any differences.
Well, for a VERY long time, Atheist have been quiet and sit in the background. With every generation, more and more indoctrination of children with religious beliefs were also peppered with lies that our Founding Fathers, were ALL Christians and they had intended that our Nation be Christian based as well. This is not only historically inaccurate, but sets the stage for Public government funded systems to be more Christian based and less secular as our forefathers REALLY intended.
It is only now that Atheist have more of a voice, that we start to use it, and Theists are liking this new "Backbone".
