Since our resident CAIR apologist seems to be taking a vacation, I will attempt to fill his shoes.
The girl should be beaten, she is attempting to leave her husband. Worse, any future man she commits sin with will be committing adultery! We cannot allow such a corruption of our values! The child must be publicly whipped, 100 lashes, then sent back to her husband to perform her proper wifely duties. If she is unable to please her husband, he is within his rights to beat her, and bring in new wives and force her to watch him pleased properly, so she knows how to do it right.
I nearly puked I was laughing so hard as I typed that, I wonder if anyone thinks it was a serious diatribe. Before anyone even needs to ask, yes I basically regurgitated random Islamic rants.
