You only feel that way b/c typically in a "mano y mano" situation, a woman would be foolhardy to take on a man. And likewise, even if the woman "starts" it, the man, IMO, has a strong imperative to refrain from battery unless he's in iminent danger of life or limb and cannot retreat.
DV, unfortunately, is not simply about fisticuffs. Oh, were it THAT simple. What if a 4'11", 95 lb. woman, pissed off at her 6'4", 240 lb muscular husband for whatever reason, takes a hammer and brains him while he's asleep? Is THAT somehow OK or even mitigated due to the gender of perp vs. victim? Yet many so-called DV or "Womyn's" advocates, rather than condemn such an provoked act of violence as assult with a deadly weapon (ADW), or even
attempted murder, will strain credulity to somehow justify the female perp's actions and blame the victim!
There's no easy solution, and getting Government involved to the point where normal jurisprudence and long-standing legal principles have been all but abolished (like innocent until proven guilty) has likely created far more problems than it has solved.
