Dangers of sex remain the same, true. But, as a teenager you simply do not have the brain to forsee what those dangers are and what it might mean for your future.
This is not a mentallity issue, but a scientifical issue, because brains simply have not grown enough yet.

If it would be a scientific issue could you cite papers to back that claim up?

What the way you measure in a scientific sense "being able to forsee the dangers" that not possible with any 15 year old but is possible with every 18 year old?

There's good research that adults have inbuild biases that make them overestimate the joy that getting children will bring them.
The reason why two adults decide to have sex is usually not because they made a long rational analysis but because they feel emotions of love.

1) It has been scientifically proven that teenage brains are run by the amygdala, the emotional center of the brain. They primarily make emotional decisions.

No, neuroscience isn't as simple and a statement like that should let anyone how knows a bit about neuroscience cringe.

Well, that's your knowledge, but my knowledge is that I am very grateful to have been protected by the adults around me from being ♥♥♥♥♥♥♥ by an adult when I was a child.

If you in fact wouldn't have made the decision to sleep with an adult I don't see how your personal experience is relevant to the question of whether those children who do want to sleep with adults like lasti when she was 14 should be allowed.

To take some recent examples in US history, with which I am most familiar, I point to the feminist movement, civil rights movement, and most recently the environmentalist movement. And to take one international example with which I am familiar, the HUMAN RIGHTS movement. Children all over the world should have the right to their own bodily and mental integrity until such an age as they are capable of making their own decisions!

It's interesting what the "right to their own bodily and mental integrity" entail for children.
It's basically about a certain vision of how children should be that's enforced by the state.
According to the universal human rights charta children have the right to compulsary primary eduction.
The philosophy of unschooling goes against the universal human rights charta.
In the same sense children have the right not to be allowed to make decision about their own sexual lifes.

Innocence is has become a major Western value. People want to protect the innocence of children by not allowing them to make bad decisions like not learning math or having sex.

McCain had been regarded as hero because he was a prisioner of war.
After WWII Russians who the Germans took as prisioners of war got sent to Sibiria for letting themselves be captured.

Innocence isn't a value in the Arab world and the Iranians didn't understand why the Brits considered those people the Iranians detained at their borders to be heros after they got released.

I don't know much about African Christian values but I would guess that innocence isn't that big over there.
