a male punched a female down to the floor or otherwise used physical violence until the female had no more ability to defend herself, and then the guy ripped apart clothing and forcefully inserted himself, fending off or forcefully countering (perhaps by preemptive hitting to weaken her) her attempts at defense (if any by that point) while just painfully (for her) enjoying his forced sex, control, cruelty, dominance and the humiliation / despair of his victim?

One major problem with communication on this issue is that the quoted text is not how sexual assault tends to appear in the real world. If that's the definition of rape or sexual assault, then what happened in Steubenville wasn't rape or sexual assault. (Just to be clear, I think what happened in Steubenville deserves to be criminalized as sexual assault).

Here is one analysis of the sociological research on rape. In brief, in a survey of ~ 1800 college students, 6% said yes to questions like:

Have you ever had sexual intercourse with someone, even though they did not want to, because they were too intoxicated (on alcohol or drugs) to resist your sexual advances (e.g., removing their clothes)?

63% of the folks who said yes to those questions admitted to having done it more than once. The mean for that group was 5.8 incidents (median of 3, so some big outliers are skewing the mean).

In a study of ~ 1100 naval enlistees, 13% said yes to a similar question, with 71% of the yes-population admitting multiple incidents. In that research, 61% of all the incidents were based on intoxication alone, with no threat of force.

That looks nothing like "male punched a female down to the floor or otherwise used physical violence until the female had no more ability to defend herself." So if that's what you are looking to prevent, you aren't trying to prevent the thing that seems to be happening.

In short, "He was drunk, she was drunk" sex is a hard problem for policies based on consent and capacity to consent. But it looks very little like "He waited until she was drunk, then took her somewhere private, and had sex with her, knowing that she wouldn't have said yes if she were sober. And he attended the event planning or hoping to do that to some woman."
