(TW for description of rape)

I believe you may have misread the article somewhat. The first victim, whom Jezebel calls Grace, was filmed without her knowledge, and was too inebriated to even remember many of the events of that night, which does somewhat imply that she was too drunk to consent. Her alleged rapist does insist that he was equally inebriated, but, as Grace herself notes, he was not so inebriated that he could not take a video of the alleged assault, which, again, was without her knowledge or consent.

the third one even said it looked like she was enjoying herself when she saw it.

"Amber" (see below) does remark that "If I wouldn't have known [Grace's] side, you never would've known [that she was being raped]," although Amber herself does not that Grace appears to be "screaming." In any event, the injuries to Grace's genitals were so severe that she suffered bloody stool the following morning.

The third one smoked some crack and skipped out of church to have sex with the guy only to reget it later

Of the second victim, whom Jezebel calls Amber, she does not recall using cocaine; she was given pills from an Advil container by her alleged rapist, who later gave her a "blunt" which "sounded like there was glass" in it, which may have been cocaine or not. Certainly she did not "have sex with the guy only to regret it later," as you suggested in your original comment. In fact, she was taken to his house in a state of semi-consciousness, as she describes it. She did not want to go into his house, but he convinced her to do so; once he got her onto his bed, she lost consciousness completely, and was only woken by him anally penetrating him. She repeatedly said no, tried to make noise to wake someone else in the house, and asked him to stop; Amber remarks that he laughed at these attempts, and ignored her obvious non-consent.

The first one was his girlfriend who gave him sex everyday at lunch before and after her "rape" when he tried to put it in the exit hole.

The (chronologically) first victim, whom Jezebel calls Katie, did indeed have a brief relationship with her alleged rapist, in which they would have sex in a bathroom during lunchtime. I certainly would not describe it, however, as "giving" him sex; I would even go so far as to say that whether or not it was consensual is dubious. Katie says that he "pestered" her for sex, even "demanding" that she go into the bathroom with him. On the occasion of the alleged assault, she says that he "forced" her into a corner and ignored her physically resisting, her clearly saying no, and her protesting the pain. Afterwards, he ordered her to get over her shock and pain and go to class as if nothing had happened. The article does not mention whether or not their "relationship" continued after the alleged assault, but then, that really isn't the point.

And it still makes the guy look like a saint!

I don't think it makes him look like a saint at all. I think it makes him look like a rapist and a bully. He supplied a young woman with drugs, anally penetrated three people who were either incapable of consent or actively saying no, and who videotaped someone performing sex acts without their knowledge or consent. Furthermore, as Katie describes, he convinced someone at the high school to seize her by the hair and smash her head into the floor. Afterwards, he even texted her, "You deserved that. I made that happen." This behavior is classic bullying and intimidation: telling one's target that you have the means of tormenting and further hurting them if you don't get your way.

All in all, I applaud the knitting circle of Norman for campaigning to bring this case to public attention, I further applaud the student who organized and, by the time of this writing, staged the walkout, and I especially applaud the young women whom Jezebel call Katie, Grace, and Amber, for having the bravery to come forward and tell their stories.
