Perplexing question.

 But with that observation, there's more venues that just those two.

 I dunno, is there a difference?

Heinlein wrote a lot of his social and political philosophy into the
characters in his books.  He also wrote a lot of it in his own name.  The
former got read often.  The latter, not so often.

The quote above, in my opinion, is one of his more bogus ones for a couple
reasons:
1. If you violate the rules, you don't retain the freedom to do so again for
long.  There's no quicker way to lose your freedom than to abuse the rules
that your society believes are right, no matter what the society, or how
silly the rules.
2. While knowing you are morally responsible for everything you do is a very
important point, it's not freedom.  No moral person, or one that accepts
responsibility for all of his own actions, is as free as someone who can
blame his immoral acts on someone else.

Heinlein wrote as he thought.  Most of his SF was social commentary in
a fictional package.  Starship Troopers isn't a was story.

Now Friday, there's an interesting one.  The man got kinky as he aged.
Although some people say that his wife actually wrote that one, as
well as a few others.
