Heinlen is a pompous twat that preaches his off-brand ayn rand ripoff philosiphy through shallow mary sue self-inserts that are never wrong, tell it how it is and are also perfectly competent, virile, have huge dicks and are somehow the most eminent philosiphers of their time. . His prose is juvenile, clunky, and artless . His characters are shallow and one dimensional. Worst of all, he just never stops ranting and preaching about the evils of communism.

It’s cold war era slop by mediocre propagandist who somehow became convinced of his own greatness.
