How not to properly satirize wife-beating

I would be grateful if someone could explain to me the redeeming satirical message underlying Robert Fiorentino’s instructional video, “How to Properly Slap a Woman.” I have three theories:

  • the makers of this video misunderstand the nature of satire, i.e. that it should embarass those who espouse the beliefs being lampooned
  • the makers of this video think misogynistic partner abuse is worth the chuckles
  • the makers of this video are so subtly criticizing a culture which views wife-beating as quaint, that their critique is escaping me completely.
