This is a tough one for me as I am offended that a girl that age would go to a party, get drunk, go off with some boys to a room by herself, go for petting and then yell rape when penetration happens. I am also offended that a boy would get drunk, play with a girl but then not accept no meant no and stop right when the girl said it even if she had been a tease. My viewpoint on this is probably colored by my old age. I can relate to this story more from my experiences in the past than what it might be like in today's culture.
I taught my son, when we were discussing sexuality in his teen years (over 20 years ago now) that if he was to be making out with a girl, going too far, and at any point she said no, that meant stop right there. Never see that girl again if she was playing a game with turning him on and then off; but stop.
I taught my daughter (she's older than him) you do not go into a party and get drunk with a lot of other drunk people as that's just plain not smart. You don't play around with sexuality with any boy unless you mean it and know where it's going. It's mean to go so far and then stop if that hasn't been made clear in the beginning.
My father taught me you don't tease men because it's not only a vicious thing to do, a power game for women, but might lead to consequences you don't want. He always said dressing too provocatively was the same way but remember that was then and today it's hard to find clothing for young women that isn't provocative. His take on that was you might turn a man on by what you wore and it won't be you he goes after; so you use modesty for the sake of all women not just yourself.
Are these antiquated attitudes for today?
It is quite possible this boy would have never had any repercussions if he had not been black, as some are accusing, and she had not been white; but to me this one does not sound like an issue of race. It seems more likely to be one where sports heroes are given more latitude to do things than anybody else. In little towns, those sports teams are everything and the good players are heroes no matter what they do. That viewpoint has created some real monsters in the sports world because they are let get away with anything. That's not okay.
It also seems wrong for the school and community to have tormented the girl after the fact. She used poor judgment but the boys did too. Teaching young people about sexuality is important and unfortunately a lot of righties want it all done in the home but some homes won't teach it-- what then?
