using the logic in your second paragraph you could argue that people having sex with children are just following their preference. which in effect they are, so if you dont see the difference between a midteens girl and a woman, as its just personal preference, how can you argue that someone that someone attracted to younger than that is wrong? if its all as you put it, personal preference?
Because:
If your preference is teen girls, and you have sex with an 18 year old girl, you're not hurting anyone, assuming the consent was freely informed.
If your preference is mature women and you have sex with a 60 year old, you're not hurting anyone, assuming the consent was freely informed.
If your preference is Asians and you have sex with a Vietnamese girl, you're not hurting anyone, assuming the consent was freely informed.
BUT, if your preference is children and you have sex with a child, the consent will never be freely informed because the child is too young to have any understanding of sex and therefore does not have the capacity to consent to it. Therefore you most likely
are hurting someone, namely the child!
It's about capacity to consent, and theoretically it's not limited to children either. If you have sex with a person who is suffering from a mental condition which renders them incapable of making decisions, they will not be able to consent (or otherwise) and therefore it will be seen as rape. In this latter case the law is not punishing a person because he is attracted to people with mental disabilities (as bizarre a hypothetical as that sounds), it is punishing him because he had sex with a person who did not consent (because they
could not consent).
Similarly the law isn't there to punish child molesters because they are attracted to children, it's there to protect children because it is accepted that children can't consent to sexual relations and therefore sex with a child will always be non-consensual.
