The possiblities are endless. Think about possible 'honorary marriages'. A public personality could be married by his or her entire fan club membership. Or, a future dictator could marry the entire country population.
See post #10... I am interested in all of your thoughts on it...
On the other hand, there is no example anywhere in the world and at any time in the past of 'homosexual' families. We know that people used to seek pleasure in fornicating with children or humans of the same sex, or with animals, or corpses, or with themselves but such practices never turned into 'families'.
The 'homosexual family' would be something completely knew and probably impossible to sustain. Its only drivers - tax and other 'welfare society'-type 'benefits'.
