I'm not.
And it gets even more confusing. In the NEC, "bond" refers to an actual earth connection, "ground" as the fault return path (the "third pin" being the most common example), and then you have the component's internal reference ground which has nothing inherently to do with either of the previous two.

Oh no!
OMG!
CSA might actually be clearer! Don't tell the Americans!

CSA:
"Ground - a connection to earth obtained by a grounding electrode"
"Bonding - a low impedance path obtained by permanently joining all non-current-carrying metal parts to ensure electrical continuity and having the capacity to conduct safely any current likely to be imposed on it"
"Bonding Conductor - a conductor that that connects the non-current-carrying parts of electrical equipment, raceways or enclosures to the Service Equipment or System Grounding Conductor"
etc.
obviously battery operated equipment does not necessarily need to be bonded to a grounding electrode to operate or work safely.
cars don't
airplanes don't
ships don't
etc.
