Odd lingo used in abortion debate.

[Kagatob]

While I know this thread will devolve into the actual debate, I'm not posting this to argue towards or against abortion itself, I can't help but notice whenever the discussion of abortion happens you consistently see the subtopic brought up about "Victims of rape and victims of incest".

Why are these treated as two distinct separate categories? If someone is a 'victim' of incest and it results into a pregnancy is it a stretch to call that a subcategory of rape? If the incest was consensual then the female involved isn't a 'victim' so why is there the special categorization?

Prease exprain.
