He isn't talking about lowering the age of consent, he's talking about redefining it so that it makes more sense.

Look at it this way. It's easy to say that older men who have sex with teenagers are predators, and should be punished. He himself says that. But how do you define "older men"? Or even "older women"? How many of those young girls were impregnated by boys not much older than they were, who aren't in much- if any- better condition to judge risks than they were? Does treating one of them like a criminal make sense? If any punishment should be metted out, shouldn't it be to both kids for doing something unacceptably risky?
