The Problem with Christians

[AJW333]

I'm not in favour of child or adolescent sex or marriage, but I would be interested to know from an evolutionary point of view, why it is wrong for biologically able people to engage in sexual activity before the government-approved age. If you have sexual maturity, why is it "wrong" to use it? Doesn't natural selection indicate that sex at 12 or 13 is normal?

The push to raise the age of consent is only about 120 years old.  The age of consent was 7 years old in Delaware in 1895.  There was no lower limit during slavery times, which is one of the reason the slave owners fought so hard to retain slavery.  

Full penetration sex with young girls is very damaging physically, especially if they get pregnant because their bodies are not large enough to carry and deliver full-size babies with major damage to themselves.  In addition they are not emotionally developed enough to raise a child when they are still children themselves.  

A lot of people try to pass this off as an ancient practice but a number of people you might know had grandmothers who were raped when they were seven years old or younger.

I agree with your observations here but what about the 14 year old male having sex with a 22 year old female? What is the damage here?
