Heinlein was…rather directionless on his politics. I think it was Clarke that once remarked that Heinlein’s politics depended on who he was sleeping with - which is why you get weird whiplash from the anti-governance free-love (and incest and racism) in Methuselah’s Children and Farnham’s Freehold to a full throated defense of utopian fascism in Starship Troopers.
