I have to agree.

I have bent aluminum parts all the time. Ever notice how an aluminum bottle cage is quite flexible? I have straightened out bent aluminum rear derailleur hangers frequently. I have bent back aluminum handlebars (not much, just slightly tweaked ones). I have bent/banged back into shape, aluminum car rims that whacked a good pothole or curb.

Granted the amount of bending an aluminum part can take is not quite what a steel part can take before failure but aluminum is definitely bendable.
