On one of your points:

Ethan: "Prepubescents are just very rarely interested in sexual activity, and if they are it's more a curiosity than passion."

This is incredibly false. Rampant desexualization in our culture and suppression causes repression.

Also you are wrong on this:

Ethan: "Young teens may have an intense desire, but they can easily wait a few years for sexual activity with little harm (or do it with peers -- laws restricting sex between kids of similar age are insane). On the other hand, sexuality is so important to adults that it trumps risks."

Young teens have a sexuality that is often stronger than their adult counter parts and biologically as important.

Do you make things up just to prove your own points? It's not a good look.
