The sky would not fall down if we normalized it, and I have prepared some rebuttals to the conservative arguments below.
The prudish a priori idea that sex is inherrently bad or dangerous for kids is the root of most arguments, and calls to emotions are why pedos aren't even allowed to argue their case in mainstream avenues. Let's go through the usual arguments now:
1) kids could get physically hurt
They can get hurt playing sports too. Wear a condom, educate in the practice safe sex, don't insert big things into tiny places and stop if there is pain for either partner. You're gonna learn that shit sooner or later so you might as well get a head start over your peers and be wiser sooner.
2) kids can get emotionally hurt
Again, that's part of life. Might as well get a head start on learning human behavior, and the routinr breakups, so you'll be stronger/more mature when you're older. And who is to say early sexual play won't help them emotionally? (There is some evidence for that.)
3) society makes kids emotionally hurt if it comes to light they were "sexually abused."
Agreed, but only because we tell them they were abused. If you didn't tell them that, they wouldn't feel abused, and wouldn't internalize the blame. When you tell them it was wrong and something wrong was done to them, they internalize it and feel bad, and develop a victim complex even if they had felt empowered and loved before.
4) It's against the law.
We're on a site that contains piracy and you're gonna talk about upholding laws on convention alone?
5) It hurts the more mature partner.
Agreed, because our norms punish the so-called abuser even if it was consensual or beneficial. Without those norms it would not be an issue.
6) kids need to be protected from sexuality.
Why? Give a good reason that doesn't appeal to Victorian or Puritan standards of morality?
7) kids are naturally innocent, have no sexuality, and don't mastur-
8) kids can be manipulated by older partners
This one is legit. Certain countries used to only allow sexual relations with kids if the parents trusted the person enough to agree, so you would need to get permission in the same way that you get parental permission for early marriage. On the other hand, this is irrelevant when the two are of a similar age. And there may be evidence that an older partner, day a tutor, could set a positive example for a kid.
Moreover a retarded adult and an especially mature/smart kid might be on the same level. Emancipated minors should also probably be allowed to do it.
9) CP is danger-
Beware of your excitement lest you tumble down the slippery slopes.
10) we shouldn't teach or encourage kids to have sexuality. They need to be nannied and kept innocent for as long as possible.
That usually says more about the desires of parents to control their kids, than about what the kids actually want. This is a normative position that should be evaluated carefully.
That's enough examples: I warned you about taking the blue pills bro...I warned you
