Contextual truth perhaps, but there are many types of synthetic rubber compounds and aluminum alloys and ethanol blends. Modern pump ethanol has drying agents to keep an actually 100% neutral substance (read, non-caustic) from interacting with impurities of gas (cheifly water) and starting a corrosive reaction.
Can ethanol cause minor oxidation on raw aluminum under certain conditions, sure. Does this really apply to the context of our common hobby? Well, the proof is in the pudding.
