Given our cultural experience and also the merely - "Scientific-like" nature of the er social sciences.
My opinion is that - we CAN'T conjure up an 'unbiased assessment' of something as convoluted as the topic of Sex. Any more than we can escape the fact of our own unique series of experiences, in coming up with opinions - not really.
Wisdom would be required to judge ANY case and such ideas as, "from 12-14 THIS is correct behavior but if One is 20 then.." - are at least better than Black/White. I liked Ben T's comment on the rather less dogmatic Rx in Canada -- must have been fewer Puritans migrating northward.. in the Salem trials days?
Sorry but - 'wisdom' can not be codifed, and it doesn't even approximately follow from perusal of a Titanic-load of textbooks either -- especially from the "social sciences". 'Law' deals with averages and mostly - the LCD. With that we are stuck. And that is apparently its guaranteed imperfection, whenever the theoretical-shit hits an actual fan.
