It is no more intrusive than atheistic science. It is also no less reasonable. 99% of scientific endeavor takes place without reference to either assumption or philosophy. Theistic science simply takes for granted that the universe is intellgently designed, and therefore sensible, comprehensible, and purposeful. It is a general approach that yields good fruit. It does not have to re-assert theistic assumptions at every turn. If it did, then it would be intrusive. Do you understand what I mean by intrusive? It means, to use a figure of speech, beating a dead horse.
And what you call a sideshow might be central to another group.
General science classes have taken place for thousands of years under the assumption of intelligent design and a universe created by God without being hijacked by religious dietary issues. Bag the red herring, please.
Takes for granted.
Okay, thanks for settling thousands of years of scientific inquiry for us. It's not science unless it makes sense...meaning, fits into your theory...is comprehensible for people with no background in science and serves the purpose of advancing our knowledge of God.
This is what many of us mean when we refer to the complete inability of the ID crowd to exercise honesty when it comes to this subject.
