You want Bristol to be a nice, average teenage girl, but on the issue of sexual morality “average” clearly trumps “nice.”
Polish it up any way you like, Bristol’s interview, and the attitude behind it that she really only erred in timing, damage Sarah’s ability to speak credibly on things like abstinence—Sarah herself concedes this.
“Average” clearly trumps “nice.” Huh???
To quote our Dear Leader, to judge the morality (sexual or otherwise) of another is ‘way above my pay grade.’
