Because once ID is what is taught, and believed, virtually -all- research in biology grinds to a halt since every currently unanswered question becomes answered by "the designer did it"
How many people would actually believe it? Won't their be any naysayers? Why do you imply there will be a "winner takes all" outcome to the struggle between evolutionists and IDers?
But here is my underlying question
As I've said above, ID is news to me. For 40 years I've been comfortable with a personal belief that any evolution that has taken place has occurred within a Universe set up by God, which operates according to His rules.
I'm an average person, who's skeptical of people who need to pound their opponents into the ground.
Like other average people, I find it necessary to cover my ears, when someone is ranting.
The evolutionists need PR lessons.
