Footloose defintely hasn't aged well
Ariel is beaten (and possibly raped?) by her jealous boyfriend. And the movie kind of glossed it over as most of the community is overly concerned about dancing being brought back into town. And there's if I'm not mistaken, a scene just after that particular beating where Ariel shows up out at a high school sports stadium to talk to Ren, and she's all bruised up with some bandages on her face.
Ren's main concern is about the possibility of being expelled for organizing a dance for the senior class instead of what just happened to Ariel. This is Ariel's main concern too, as well as warning Ren that her jealous ex is coming to beat him up as well. Then, the jealous ex shows up and threatens violence, and Ariel puts herself between them allowing Ren to escape while she gets beat again.
And for the sake of the argument, there's only one token POC couple that show up at the senior dance at the end of the movie.
