So his goals were libertarian, but I can't help thinking his intended means to achieve them would wind up, er, not doing so at all even slightly.
On that note, Heinlein wrote all sorts of weird, contrarian themes into his books. Many of them pushed against the prevailing social norms and beliefs of the time, from sexual norms to ethics to race relations. Trying to pin down his actual beliefs is difficult because he would often write one book taking one stance on an issue, and another later with a totally contrary stance. Often when I read Heinlein I find myself strongly disagreeing with what he's putting down, but fascinated with the question or angle being posed/presented.
And then, of course, your comment about people being unwilling to even consider the thoughts of those they disagree with steps in.

Director wanted a thing, and the subject matter fit was irrelevant. shrug. I call it "Bug Wars", and as such it's a well animated B movie.
There are alot of people who made the transition from a socialist to a more right wing position.

His isn’t necessarily a worldview I subscribe to, but isn’t worthy of being dismissive about.
