While the movie was definitely a fascist take on the universe, considerably Nazi-esque to be more precise, the book was more anti-communism than pro-facist.
Still, is the idea that rights and freedoms should be earned through individual sacrifice such an undesirable view? Personally, I believe it would lead to a better, considerably more coherant society where those that shouldn't have a voice, quite simply, don't.
I so love when people try to subvert my idols for their own gains.
Read the novel again - they never pulled this ****.
Everyone has the right to earn their citizenships - the only reason you may not take the test is if you're mentally incapable of doing so.
Citizenship however doesn't equal freedom - it equals responsibility, and the power to go with it. Citizens are granted the power to decide for everyone by casting their own vote on issues. Everyone can attain this power provided they also accept the responsibility to go with it, which is putting the life and wellbeing of everyone else before your own.
However non-citizens aren't slaves or restricted either. It's power you gain with Citizenship, not freedom.
They have the rights for freedom more than anyone else in our history....with the aft forgotten ammendment, that in a JUST society your freedom may never become other people's restriction.
They can, and often ARE saying whatever they want to about the goverment.
What Heinlein DID dispute, is the LIBERAL BELIEF in INHERENT GOODNESS.
Liberal thinking assumes that humans are inherently good and just, and therefore wihtout restrictions to warp them, they're bound to live a happy life in a just society.
He claims, that this assumtions is entierly FALSE (which I strongly agree with), that humans must be thought what goodness is for the sake of society.
He never said, that it would be the state's bussiness to do so, or that there is a ONE TRUE MORAL CODE to adhere to.
He actually says counter-wise, that from scientific point of view morality is bull****; a code handed down accepted out adherence to customs without any (scientifically) prooven beneficial effect or understood mechanism. So he also dethrones CONSERVATIVISM.
What his rhetorics boils down to is the need for POWER to be equally weighted with RESPONIBILITY for society to function as a whole. The need for accountability, and especially among those in power.
So if you want to bring up Heinleinen rhetorics, start your purged at the top of the ladder, where the power and the hypocrisy are at their strongest.
Only regulate the others if you managed to clear that stable, which is probably the reason why Heinlein's utopia won't come to pass until another psychological innovations takes over modern societies like the idea INDIVIDUALITY did during the Middle Ages.
