Metering is a religion for a lot of people - lots of emotional responses for what one would think would be a very dry subject. All you really need to know is that incident meters read the amount of light falling on the dome of the meter and reflected meters read the amount of light reflected or transmitted by the subject -- so to dumb it down, with incident meters you are reading the brightness of the light and with spot meters, the brightness of the object.
