I agree. No need for the quibbling. The name Al Qaeda had it's origins from the OBL encampment (The Base) in Afghanistan, or so I've always believed.
I think you guys are just riding Skeptic's ass. It seems to me he was pointing out that Arabic lacks a wide variety of roots, so context is often needed to determine meaning for a specific word. He used a well known example. He explained that in the discussion here regarding killing there does exist enough variety of language to provide for reasonable translations.
It's funny that the so-called experts in Arabic don't seem to demonstrate the same grasp of English. Base has its roots in basis, which in turn has its roots in <wait for it> a place one stands. In English base has 25 definitions for the noun form, so you really do need context to pick the right translation, just like you need to know the context to make the right translation for Al Qaeda.
This was offered in contrast to explain that context is probably not an issue in choosing the right translation regarding killing. In English one may need context once you get beyond terms like kill, murder, assassinate and slaughter (to name a few). Words like neutralize, extinguish and eradicate can mean kill in the right context. They can also mean other things that don't involve killing. For example:
I call upon my skeptic brothers to (kill, murder, assassinate and slaughter) politicians who support teaching creationism in public schools.
I call upon my skeptic brothers to (neutralize, extinguish and eradicate) politicians who support teaching creationism in public schools.
Somebody could play games with the translation and give examples of how people use the terms neutralize, extinguish and eradicate in the context of killing and claim that the latter was a call to violence. Skeptic was pointing out that this wasn't the case.

It's not discussed in "The Looming Tower".
