Allow me to be the first to challenge this propaganda.
We drew our line at 18, as good as any arbitrary line, so of course there will be gray areas like a 17 year old girl and her 19 year old boyfriend where no harm is really done. But convicted pedophiles guilty of more than one count SHOULD RECEIVE SWIFT DEATH PENALTY. The world would be a better place.
And many states have provisions in the law to cover that sort of thing. I was a juror in a 'statutory rape' trial, and the whole age of consent business was explained in excruciating detail.
