It's not even flat out true. From what I've found, Iowa is the only state with a clear cut law about recognizing only the mother as a victim in a violent crime. In the majority of the other states, there are separate charges for violent acts that injure/kill an unborn child. Eight states have partial coverage, dependent on fetal stage. Other states don't have a law, but I don't think that necessarily means you won't be given separate charges.
In federal and military crimes, the Unborn Victims of Violence Act comes into play, at any fetal stage.
But usually when a pregnant woman is a victim of a violent crime, the penalties are upped with regards to the crime. So no, it's not an attempted murder charge, but it's a recognition that there is a reason it's worse when you attack a pregnant woman. Wonder why.
Northern Ireland, Wales and England, Australia, and Hong Kong all have "child destruction" charges for causing the death of an unborn child, but it looks like it's usually after a certain point in the pregnancy, and they have to prove the assaulter intended to do it. Funnily enough, despite these laws, there have been some testimonies of women in those situations who mourn the loss of their child. Weird that knowing their unborn child wasn't human because they weren't born yet didn't help them. Weird how instead a lack of justice for their child hurt.
An incident in Japan is causing social and legal debates about their current legal system in regards to unborn victims.
The statement is truer on a global scale, sure, but if we're going with the "even the patriarchal world realizes it!" we could also look more into what a patriarchal world believes. Like how some very patriarchal worlds believe that women aren't human . .. . or are inferior to men . . . . I'm sure we want to trust their opinion on this matter, right?
I'd actually opt for the more feminist position here, which appears to be unborn victim laws. These laws are not just justice for the unborn victims, but for the mothers who then have to deal with the pain of losing a child. Or finding their child had received permanent damage, which can pain mothers, like it would with any other child who suffered a violent crime and survived. What mother wouldn't want justice in those scenarios? Really, the only reason to not support them is because you've based your belief of abortion on the legal system and introducing such laws might eat up ground there. Honestly, which is the more compassionate response- denying mothers justice for death or injury of their unborn child, or giving them that justice?
