bottomline is what do the people find offensive about this video ?
if its the fact that a alleged fornicater is being punished by public lashing then they need to reevaluate their opinion on shariah and islam itself
Unless you can prove that she was truly a fornicator, rather than just an "alleged" fornicator as you yourself have admitted, I would advise that you, as a muslim, distance yourself from this video, as supporting it might very well lead to more mismanagement of sharia execution, for which the Taliban have been famous for over a decade now as documented thoroughly with years of brutality and unjust leadership over a hostage society.
Secondly, if your daughter was caught winking at the boy next door, I wonder if you would be ok with this same kind of punishment, done EXACTLY the same way (i.e. being held down by men, burqa raised to expose the butt-side of the shalwaar, and thrashed over the butt with a crowd of MEN, and only men, standing around to watch for their entertainment)?
