It'd hardly be worth noting, if not for the fact that the only 9/11 "truther" I've seen pop up on either side of the creationism/evolution blogosphere is Bilbo, formerly of the pro-ID Telic Thoughts blog. Bilbo defended his regular postings about how 9/11 must've been an elaborate plot by whoever, writing:
I don't think that 9/11 truthiness resembles anything, whether it be ID or "Darwinism". Yes, ID creationist Bilbo was (and still is) a toofer (and we've debated on this issue). However, there are toofers on all sides of this debate, such as philosopher James Fetzer, co-editor of the ID critique published in Synthese recently.
