I wonder why it remains such a contentious issue in ttwd? Isn't the act of the face slap just another tool in an arsenal of tools designed to deepen submission and lets face it (sorry for the pun), thrill a Dom/me to see their subbie react in whatever way they might? I find it an unusual argument to align the discussion of the face slap with the conditions of family and domestic violence. Sub women and men in ttwd - bdsm are consensually engaged in many acts which the mainstream (vanilla) world would view as abuse.
I would argue that statements about women being elevated to strong, beautiful beings, venerated by their Doms for their gift of submission, might be viewed as an expression of the battered wife or even Stockholm syndrome in the vanilla world. So why is the face slap sometimes placed in a different category to say a caned bottom left with bruising, welts and in some cases broken skin?
The key is consent, as with everything in ttwd. The face slap is no more abuse in a consensual relationship than the cane, or a hand spanking. There appears to be an agreement that the power of the act is different in some way. A suggestion has been made that the face slap is 'personal'. It's meaning holds a different and perhaps deeper resonance to the individual receiving the slap. I have noticed though the struggle that women have in accepting the face slap as a 'normal' part of ttwd. Maybe it's this difference of power imbued in the act that encourages questions of it's legitimacy; that the face slap is an act which is abuse.
Todays picture is a bit flippant and is not design to resemble uncontrolled, non-consensual abuse in any way ;).
