There are cultures, currently, in this world, which would take the case of a young virgin being raped and think that her lack of virginity reduces her value, which may compel her to marry her attacker because that's the best she can do now; and, in extreme cases, this rape victim may be murdered by her father or brother in an honor killing because she's no longer pure.
There are also cultures that do what they can to provide rape victims with counseling and pursue their attackers so that their attackers can be punished to the full extent of the law.
It stands to reason that, in this case, one culture is better than the other. If you disagree with that, you're a moral monster.
If you believe that no cultures are better than others, you have to either believe that the ethics of rape are relative to culture; or, you have to believe that every culture that defends rapists has redeeming features that equalize them to every competing culture. If you believe the former, you're a moral monster. If you believe the latter, you're an idiot and probably a moral monster.
