Here's a decent summary of 'Intelligent Design', as far as what they're trying to sell:
http://www.everystudent.com/wires/evolution.html
The crux of it is this (in my opinion). Creationists fought and lost. So they decided to change tactics, if religion wasn't allowed, then they'd pretend it was
scientific. When people point out that it's really RELIGION (because it's creationism per the bible) they scream that their "belief" is just a valid as evolution "belief" and try to portray them as equal in that their both just "beliefs".
This of course ignores all scientific data, except the bits and pieces they attempt to use to bolster their argument. Unfortunately...it works. People see them talking in 'scientific terms' about God. Many people believe (regardless of what you believe scientifically) that there is 'something' behind it all.
That's all well and good. But whether or not one believes that, and if so WHAT is behind it...is a matter of religion. Which we don't teach in our schools in the United States.
Well...mostly. In Cobb Country Georgia, they are going to teach intelligent design if they can. There are a number of lawsuits going on, the school board voted that "intelligent design" must be presented with creationism, both as valid scientific theories. I know the ACLU is involved, I'd imagine some other organizations are as well.
The other problem (again just personal opinion) is that some people who are for intelligent design that I've seen (not here on the JREF boards, I'm new here) play what I can only call the 'Socrates for Dummies' method. They pretend to be stupid about science, and you're forced to basically educate them, because what they're saying doesn't make sense. (Such as a "theory" isn't EVER true...they believe it's just a blind guess, or act like they do

). So you can get bogged down into being forced to deal with science basics just to level the playing field so everyone understands wtf the terms MEAN.
Then whammo, they'll start slamming things. Suddenly they
are well versed in science, and they'll attempt to show that various things aren't necessarily so. And there are grey areas in science where we're still learning more. But...they will hold ONE contradiction up as the holy grail (even when it's not a contradiction) and act as though because
one thing doesn't fit perfectly ALL OF IT must go. Which isn't the way reality works.
I'm running across more and more of them too, in the oddest places, so it's spreading pretty fast. I wasn't aware that it had exported to the UK, but it doesn't surprise me.
I'm not an expert in most things, most people aren't. However when I want opinions on something...when it counts, I rely on people who are experts, and I ask more than one. Intelligent Design...just isn't a scientific debate. It's not like evolution is under attack in the realm of science! It's under attack by religious groups...who are NOT experts in science. I'll allow that they may be experts in their various religious beliefs, but it doesn't carry over into the realm of science.
I'm probably preaching to the choir here (all puns always intended

) but whether someone wants to believe in 6th day creationism, or that the earth is on the back of a giant turtle...have fun. Just don't expect others to treat your beliefs with the seriousness a true believer puts into it...and don't expect others to have to learn it. If you want religion taught in schools, home school your kids, or put them in a private school.
Sorry, started ranting a little there. It just irks me.
