We have a soapdish next to each sink in the house, filled with typically at least two different bars of soap (I simply like variety) - but it is as crunchy-organic of a soap as I can find, never any added chemical anti-bac crap added, and frequently a soap made nearby by cottage-industry soapmakers who, BTW, make seriously fine and gentle bars.
I have four kids, and between meat grease, finger paint, wiping the schnozz with bare hands, helping the Papa maintain the cars and heaven knows what else, I think a bar of soap for the hands isn't amiss when the crud gets too thick or before the progeny grab hold of Daddy's clean dress shirt (with Daddy in it) just before he leaves for his office... And PlayDoh and modelling clay stay unspoiled MUCH longer when the kids wash off the grunge before using it! The number of colds and such has been reduced dramatically around here just by washing our hands immediately upon our return home from a jaunt "out in public" (like libraries and any place where many human hands are), so I think hand washing itself a Good Thing - just not with sanitizers, and even with soap, not constantly - just judiciously.
I have read before that those types of scientists who take and analyze samples from our environments are finding Triclosan in places they shouldn't, much like DDT and pharmaceuticals - a good enough reason in my book not to use it. I think sanitizing the skin should be reserved for special occasions like surgery incisions.
