What chance does someone who is disabled have in a conflict with a strong able bodied attacker?

What chance does a young girl living or walking alone on campus have against a bigger stronger man?

In most situations the stronger person will win. Except when guns are involved. Guns are equalizers. A young girl who is all alone with her gun or a person in a wheelchair with a gun can be just as deadly as any man with a gun. Beyond having the ability to aim & pull the trigger, muscles don't matter.

What people like you support is disarming the weak. It appears (to any sane person) that you prefer to help the criminals. You want people to be terrorized & raped & stolen from.

Criminals don't obey laws. Any idiot can see that. And there are many ways to illegally acquire a gun. It's also quite easy to 3d print them or to make one from materials readily available at any hardware store.

When you support a law that disarms people, you are creating an environment in which only criminals have guns. And good people are in much weaker positions against attackers of all kinds. People who advocate "gun control" are making the world a scarier & more dangerous place for good people.
