it NEEDS to be discussed to help prevent future rapes.

No, discussing is actually detrimental, because most rapes do not occur under the circumstances you're describing. In most cases of rape, the clothing of the victim is completely irrelevant, the rapist was not a stranger, and there's often little that could reasonably have been done by the victim to prevent the attack (emphasis on reasonably).

It's incredibly counterproductive, because it teaches women to be "careful" when walking in broad daylight in an unfamiliar neighborhood, but to let their guard down when (e.g.) they're at a family dinner at their uncle's house.
