The "debate" on whether the United States was founded as Christian Nation

Every now and then I'll see a debate going on somewhere about whether or not the founding fathers wanted us to be a "Christian Nation". The secular side will bring out the Treaty of Tripoli, which in part of it states in Article 11:

ARTICLE 11.

As the government of the United States of America is not in any sense founded on the Christian Religion,-as it has in itself no character of enmity against the laws, religion or tranquility of Musselmen,-and as the said States never have entered into any war or act of hostility against any Mehomitan nation, it is declared by the parties that no pretext arising from religious opinions shall ever produce an interruption of the harmony existing between the two countries.

The secular side also brings out that "god" is not mentioned anywhere in the Constitution.

But wait!! The Christians will say that God or "God Almighty" is mentioned in EVERY states preamble! Doesn't that make us a Christian Nation?

What I am saying today is that it DOES NOT MATTER if the founding fathers said or stated in someway that we are a "Christian Nation". The Constitution is not a set in stone/static document that can never change. Times changes, new information is discovered, societies morals change.

Here is an example. When the founding fathers drafted the Constitution, owning slaves was a very common thing, and really wasn't seen (at least by the majority of the time) as a bad thing. Our founding fathers could have easily put something in the Constitution that our nation was a "slave nation" and all people in the country had the right to own at least 2 slaves per household.

Do you believe that in the year 2009 we'd still have slaves just because it was written in the Constitution? Of course not. We would have had amendments passed that would have changed all of that.

And what does it really mean to be a "Christian Nation"? Would that mean that it would be the official religion and you couldn't practice any other religion? If you did would you go to jail, or get fined perhaps? Would that mean that the laws would be based on the Bible only? Would that mean that the only science taught had to conform to biblical teachings only? I really don't see why it matters whether or not we are Christian Nation or not. I just don't see our actions and behaviors being much different than they are now.

So all of you STOP IT with the Christian Nation stuff. It just doesn't matter.
