We should be convinced by this succinct and eloquent exposition that Intelligent Design should be taught in every high school and your summation is the best I have yet encountered. Many thanks from a Christian Conservative whose Faith is even yet capable of an upgrade when reviewing your post!
There is nothing scientific about ID so any attempt to paint it that way is a failure from the start.
The assertion that various cited examples are "irreducibly complex" also represents a failure, but in this case a failure to understand.
ID is nothing more than an opinion put forth by those who don't/can't understand evolution or those who refuse to for personal reasons.
I don't mind this being taught in schools, however. There are ample "comparative theology" classes in which it belongs.
I sincerely believe what I said..
Intelligent Design is not Intelligent..
It lacks faith in God..
Let me further explain..
I believe in God, and God's creation of the Universe..
I also believe in God's use of evolution to create all life...
What I reject is the denial of scientific endeavor, meant to help mankind explain the workings of our universe and the life that exists within it..
No science has ever proven, nor to my knowledge, attempted to prove that God does not exist, or to deny the existence of God..
( Philosophical argument and opinion is not science, don't count that as an example. )
