Lucky, you don't need to amend your post in any way...
You were very specific in saying that YOU had the following philosophy: "Nothing and no one in life is irreplaceable (except God)." Nowhere did you say that we all had that philosophy, or even that we all SHOULD have that philosophy, and no reasonable person ought to object to you airing your viewpoint. They certainly have no problem airing theirs..
And 'God' by itself pretty much covers ALL religions except multi deity faiths. You didn't call YOUR God by name, and your statement is pretty accurate for just about all monotheistic religions.
We keep looking for differences between the faiths, to better shore our own faith perhaps (mind you, if you DO have 'faith', what shoring does it need?) or to justify our intolerance of others, but the truth is, we are FAR closer to each other than we like to admit.
I can't think of a single religion in the world that WOULD argue with your statement. God, no matter what faith you follow, is 'irreplaceable' in ALL faiths.
