It's not that I have a dislike for them they are just pointless in most cases. More than that they are unnecessary. Unless you're writing a fictional novel or the like.
Well, here's where I was going with it.
I have found that people often hold principles they haven't sufficiently held up to real life possibilities. Your comments gave me the opportunity to make a point about this.
I am strictly pro-life, and don't believe exceptions for rape or incest are logical or permissible. Nevertheless, when you say, for example, that a biological father (rapist) who wouldn't go away, would be killed for messing with your family, I find that uncomfortably similar to aborting a child whose existence is perceived as messing up the family dynamics. Not to equate them morally, but you didn't say you'd kill him for rape, but rather for trying to have a relationship with his offspring, which is not in itself an evil thing.
In fact the child of a rape is capable of blowing a family structure to kingdom come, and this is why some women might choose to abort. They think of the effect on the husband who'll never accept that baby, the children who'll have to deal with the divorce, the life-altering hardships afterwards, etc.; and they decide not to carry the child to term. This is killing, but one sees their reasoning.
And I see yours, but it's still killing. The man who, after raping your wife, by some awful twist of fate gains legal leverage and even visitation rights---does he deserve to die for it?
The law nowadays is pretty screwy. His parents could get grandparent rights in some jurisdictions. Would you threaten them? If he repented and seemed genuinely sorry, would you forgive him the rape (as the Lord exhorts us more explicitly than He ever did about abortion) and kill him for the domestic interference?
Now, I don't quite believe you'd kill anybody, which gets us back to my earlier point. Folks don't always think things through.
And mostly they don't have to.
And those who do have to are mostly women.
