I sure can... would you like to elaborate when you think it is appropriate to beat your spouse?
I've never yet needed to hit my spouse. In fact, I've never needed to even raise my voice at her or give her a warning yet. So I have no experience that can give me an example of when it would be appropriate to slap my spouse.
I can give an example from a previous relationship I was in though. One evening, that woman was begging and nagging me for sex. Unfortunately, I didn't have the heart to slap her one (I just apologetically walked out as if I was in the wrong for refusing her, foolish man that I was); but that was an example of when it might be appropriate to slap a person as a form of self defense to snap her out of her coercive behaviour.
Oh, and just to clarify, there's a difference between slapping and beating.
Even slapping is abuse when it's non-consensual and outside of a reasonable claim of self defense. In the case of a woman begging and nagging for sex or touching a man sexually without his consent, I think that would be a very valid reason to slap her without causing her injury.
So EagleSmack, are you saying that there never is any valid reason to slap a person under any circumstance whatsoever?
