> but if you hit something hard enough to break a carbon frame, you'll have done even more damage to an aluminum one.

The problem with carbon isn't what happens when you ride it, but what happens by accident. Tipping a carbon bike over can cause stresses in a direction where the fibers are weak, thus causing significant damage with minimal force. Some carbon bikes are even so thin in certain places that the frame can bend if you press it with your finger.

This type of problem is not present in aluminum frames.
