Sometimes they ARE asking for it. And guys will look at clothing as a hint. If she isn’t wearing underwear & is falling out of her top, the average 19 year old male considers that a fairly strong hint that “I’m available”.
And when she is in a military dorm with a guy she invited in, and they drink together and are seen in the hallways with their arms around each other, and there is no sign of force & people in the room next to them hear no screams or sounds of a struggle, and they have sex...was she raped?
Maybe. Maybe not.
Was she asking for it?
Well, she created a reasonable doubt that she WASN’T asking for it.
Your “theoretical” woman in your “theoretical” situation may be advertising that she is available, but real women who are raped aren’t “asking for it” because of something they are wearing. Regardless, I’m getting off topic discussing this scenario.
Back to the “legitimate” rape comment by the senator wannabe, it was a poor phrase to use for sure. After reading a few sources, it does appear that pregnancies occurring from rape are quite small....not necessarily for the reason he claimed....but it is a small number. I was surprised.
