I think part of the problem here is the Christian doctrine of convincing others to join you in the movement. That's why he feels offended.
And Keith-sama...in terms of the conflict between science and Religion....It's probably because of the whole "World Created in 7 days" in the book of Genesis.
The Theory of Evolution is an example I am going to use.
I, for one, am starting to see inconsistensies with the Creationist theory, which states that animals are a certain way "because God made them to be that way".
However, based on scientific observation made over the years, Many animals have evolved over time to adapt to certain environments. Why this is so, the creationist theory cannot really explain.
So In my view, Science AND God do go hand in hand.
