Jubal looked troubled. "You've raised a hard question, Ben - but I'll give you a straight answer.  Yes, I think what those people - the entire Nest, not just our own kids - are doing is moral.  As you described it to me yes.  I haven't had a chance to examine details - but yes: all of it.  Group orgies, and open and unashamed swapping off at other times... their communal living and their anarchistic code, everything.  And most especially their selfless dedication to giving their perfect morality to others."
