It's very hard to define science—it's the demarcation problem and, in spite of what you've been told, philosophers don't agree on how to define science.
A lot of the activities of Intelligent Design Creationists qualify as science, as far as I'm concerned. That's why I spend so much time arguing against their attacks on evolution. Many of the IDiots accept common descent. Their attacks on other aspects of evolution aren't much different than similar attacks from legitimate, non-theistic scientists (e.g. objecting to junk DNA, questioning the Cambrian explosion, challenging strict Darwinism). It counts as "science" but it's very bad science and it's wrong.
All IDiots are anti-evolution but some go farther than others. If you are a Young Earth Creationist who believes that the universe was created less than 10,000 years ago, then you are not just anti-evolution, you are anti-physics, anti-chemistry, anti-geology, anti-astronomy, and anti-biology. I think it's fair to say that Young Earth Creationists are anti-science. This includes most (all?) of the Republican Presidential candidates in the United States and more than half the citizens of that country.
The only way YECs can possibly justify their strange beliefs is to assume that all the experts in all those fields are completely wrong about the fundamental concepts in their discipline. How could they possibly trust anything else those scientists have to say about their areas of expertise?
Let me introduce you to a "new voice" in the Intelligent Design Creationist world. Here's what Evolution News & Views says about him [A New Voice in the Debate Over Evolution and Intelligent Design].
There is literally a new voice in the debate over evolution and intelligent design. If you're a regular listener to the Center for Science & Culture's very popular and thrice weekly podcast, ID The Future, you have probably come to recognize familiar personalities, like ENV's Casey Luskin. (If you're not yet a listener, then you should be.) Now you will be hearing more often from radio broadcaster David Boze of Seattle's KTTH.I assume David Boze is a heavy-weight and it's okay to criticize him.
Listen to the Discovery Institute podcast where Boze defends Young Earth Creationism against the charge that it's anti-science ["Anti-Science": Unpacking a Vague & Distorted Label]. (You can click on the embedded copy below.) Note the sleight of hand where he lumps together the Young Earth Creationists with all other IDiots. His point is that just because you're opposed to "atheistic Darwinian evolution" does not mean you're anti-science.
Perhaps not. But if you believe in the literal truth of the Bible then you are definitely anti-science. You are a genuine idiot. Does David Boze do a good job of defending Republican Presidential candidates against the charge of being anti-science? Will a YEC President harm the reputation of the United States? You be the judge.
Personally, I don't think the new kid on the block is much of a threat. Is this the best they can do?
