Excessive idling can actually damage your engine components, including cylinders, spark plugs, and exhaust systems. Fuel is only partially combusted when idling because an engine does not operate at its peak temperature. This leads to the build up of fuel residues on cylinder walls that can damage engine components and increase fuel consumption.
Idling is the worst thing you can do to an engine, especially if it is cold. All the humidity in the engine condenses on the sides of the engine and the organic acids in the blowby dissolve into the water. The water then drips down the sides of the block and sits on top of the engine oil. The acids in the water attack the oil and cause it to sludge and break down prematurely.
You are FAR better off to just drive the car and get the oil fully heated and move some air through the engine (via the PCV system) to clear out the water and acids as quickly as possible. Or suffer sludging and corrosion. It's entirely up to you.
