You do realize that half the world currently lives that way?
And you do realize how many pre-adolescent children are exposed to hardcore porn on the Interwebs these day?
What's worse? Children learning about sex from prostitution-porn, or children being aware that their parents make love?
You state that, “...half the world currently lives...” in one room or tent. It is probably more than half. Do you believe we should live the same way? If so, perhaps you might wish to join DU! They seem to relish changing North America into the third world.
AFA so many preadolescent kids being exposed to internet porn versus their seeing ma and pa getting randy, I prefer the parents take responsibility and dad inform the boys and ma inform the girls, when the time is right, rather than demonstrating it in front of the kids. Knowingly having sex in front of their kids IS a form of pornography and child abuse, not a lot different from their showing internet porn to the kids.
