OFF TOPIC
I think that the culture thing is being taken out of proportion here. My understanding of the law is that 16 is the age of consent here, and, if executed properly, the marriage may only be consummated at age of consent - the girl usually stays with her parents until she is consensual age and the husband may only visit if they have a chaperon. So the whole rape thing is being taken out of proportion here because both parties to the marriage have agreed to it in the first place - this isn't India where 14-year old girls is given to 40-year old men.
However, in reality, it is rarely executed like this but, any sex that does take place, is consensual. It might qualify as statutory rape though but who's going to report it if the participants were willing and the parents consented to it?
