Tom Charette, you raging douche. The thumb is TOO a finger, you flaming bag of crap. Just because the digit happens to be opposable on human hands does not make it any less of a finger than the other digits. It just happens to be able to touch all other fingers on the same hand. A bicuspid and canine are different, but they are both TEETH. All of the fingers have a name other than 'finger'. A simple search for the physiology of the human hand would reveal that, so before you go off on somebody with some righteous indignation over a cause you believe so strongly about, it might behoove you to do the minimal amount of research to not make yourself look like a total ass. ASS.
Nicely stated, you total ass.
