Cool. I'll assume that you understand the information given at the link you provided. Now YOU may make the argument about amino acid chirality. How does that help Jennyp? Didn't she do what the article above was warning us not to accept from Creationists?
I composed #61 before I saw your #53, but allow me to amplify a bit. In truth, I think the problem is less with JediGirl that with the article itself. This article miscasts the fallacy of argument ad verecundiam into a much stronger and broader form than it is generally understood. There is nothing generally wrong with appealing to authority, so long as the authority is an appropriate authority for the topic at hand.
I have little use for creationism myself, but I think that it would be best to re-write this article, as it betrays something of an attempt to blatantly stack the deck in favor of evolutionary arguments.
