A teen is being punished because a few 'dads' had impure thoughts? I don't think it would have mattered what the teen wore if these dads can't control their own impure thoughts.
Are women responsible for men's thoughts? That's a lot of control, if it is.
Perhaps the dads need to get some professional help to overcome their impure thoughts before they act on them with their own daughters. They're the ones that should have been 'ejected' for not controlling their own behavior.
