The usual pretty crude pneumatic sex-fantasies cropped up... But women actually have a pretty dominant role in Heinlein's lunar society... It's a penal colony, and Heinlein reckons that means there are going to be far fewer women then men there - so he's come up with a system called 'line-marriage'... wherein a few women in a household share numerous husbands... And the head of the household is a woman... and women call the shots... Meanwhile, outside the home, women are treated with far more respect than they are on earth because they are so rare and precious... Obviously, he's not going to get any badges from feminists, but he does at least ask a few interesting questions about the way women were viewed in his own world...The characters explicitly reject using patriotism as a method to revolution.
I think that Prof De La Paz's 'rational anarchism' is also expressed by Jubal Harshaw in 'Stranger', though not in as straightforward a manner. Both seem to say that it's not that hard to figure out what ideal behavior should be but expecting actual live humans to live up that is impossible. After accepting that point, they both want to move on. Yep, humans are hypocritical and sometimes hard to live with. What of it? The other big point of this is that only the direst situation (near term cannibalism here) justifies butting into other people's business. Sadly, this attitude is pretty rare today. The characters explicitly reject using patriotism as a method to revolution.
