A search I did on google that I did recently has given me pause to accept that it cannot be taught. I searched "age of consent" and about half of the hits were gay sites.
It has cause me to wonder why the age of consent is such an important topic to gays.
I can answer this for you. Because in many states and/or nations, the age of consent laws have been different for opposite-sex & same-sex relations. It's considered another form of antigay discrimination & is a high priority at least amongst international activists (especially since many nations which have long-since repealed sodomy laws still have disparate age-of-consent laws - usually 21 for same-sex & 16 for opposite-sex - as their only remaining discriminatory statute, aside from marriage).
It has something to do with the concept of "prey."
