Wow, I ddin't expect much from this topic and I was still dissapopinted.
I hate having to be the one to enter "logic" into a debate, but it looks like it's my responsibility.
1.) Teenagers fuck because mother nature tells them too. It doesn't matter is societies have changed, human biology hasn't. Kids become teens, they want to start fucking, why shouldn't they? And as far as a legal consenting age? Hmn...how about 16? By then, both sexes have gone through the cornerstones of puberty and have (hopefully) spent enough time around the opposite ses to know what they want.
2.) I've heard alot of the 2 basic arguments for the simple minded: Fear, and God.
a.) "Just picture it, you're daughter is 16 and she's Daddy's little Angel. But then she starts dating the 22 year old guy, and he turns out to be THE DEVIL.
Eh. This kind of argument is sad in so many ways. Firstly, that's a "what-if". A Possible scenario. It's also a possible scenario that if a walk outside my house today, a double decker bus might run over me. Should I lock myself inside, just in case? Or should I just inhibit my teenager's natural habits because of my own self-centered, borderline schizophrenic paranoia?
b.) "God hates it when we do what is inherent in all living things to do!"
Eh, yeah...well unless you can prove that God exists, who he is and what he wants, he has no room being admitted as evidence in any logical debate. Ever.
