Why do microwaves damage circuitry?

More specifically, if microwave ovens use a frequency specifically chosen to resonate with the water molecules in foods, drinks, and whatever else if put in a microwave oven, why does it also have such a significant effects on certain metals and electronics?

Microwaves, or any light for that matter, are oscillating EM fields.  In the case of MW its on the same size order of most of these objects so the fields couple very well.

These fields then induce a current which then proceeds to short or melt various parts of circuits.
