Speaking of being a coward, I'm still waiting on your answer how a 35 year old would hurt a 15 year old any more or less than another 15 year old, or another 35 year old for that matter, Mr. "I answered all of your questions".
Depends on the situation. I'm willing to entertain the possibility that a 35 year old could possibly have a healthy relationship with a 15 year old, but given the advantages in experience, money, strength, & power a 35 year old would have over a 15 year old I have a hard time believing the 15 year old wasn't being taken advantage of and/or manipulated. This is why parental consent comes into play, depending on the state, as if the parents judge the relationship to be healthy they can sign off on it. I'm ok with that. I'm also ok with laws protecting children from adults & even find some of the laws (arresting an 18 year old for boning his 17 year old girlfriend, consensually) to be a bit silly. However, until there's a good test to gauge maturity, age is the only thing that can be used. I'm ok with that, as I believe it does more good for children than harm.
