The first major thing that I get from this are that R&J laws don't cover homoloveual relationships. Disregarding the fact that they wouldn't apply anyway (|18-14|=4; 4 > 3), that's homophobic and should be outlawed.
The second major thing is that our 'must draw line somewhere' attitude, unfortunately, makes there be no 'gradient' of punishment. If you have love with a minor that's two years, eleven months, thirty days, twenty three hours, fifty-nine minutes, fifty-nine seconds, and nine hundredy ninety-nine milliseconds younger than you, it's completely fine. Two milliseconds more is TOTALLY WRONG AND ILLEGAL. (Not that we even time births down to the millisecond.)
