I've never visited any of those sites.
Do they claim to be "peer-reviewed" in the sense that, say, Journal of Physical Chemistry is, or do they merely claim authority based on the scientific credentials of individual contributors?
Full Disclosure: Honk if you passed P-Chem...(bumper sticker)
Visit them and have a look at 20 random pages, see if you can find a subject that you know at least a little about (yeah, I know that violates the word "random"). You'll soon see the careful peer-reviewed worth of their arguments.... BUWAHAHAHAHAHAHAHA. They aren't designed to appeal only to the ignorant and credulous one bit. No Sir. That isn't cod-scientific flim-flam with a thin veneer of observation. Not at all.
In fact the challenge is on to find a good honest argument that stands up to critical knowledgeable scrutiny on ICR, AiG, or DrDino (don't bother with the last one on that list, even the other creationists disown it for the poverty of its science). What I haven't managed to work out is whether the authors of those sites are lying scum, or whether they are blinded by literal adherence to their holy book.
