In my youth I read just about everything Heinlein wrote....
As an adult, I came to realize that Heinlein was Godless as are most sci-fi writers....which ended my fascination of SF.
Most sci-fi writers do seem to be indifferent or even sometimes hostile to God. Despite that, some of them are still great, at least in my opinion.
R.A. Lafferty, Manly Wade Wellman, Cordwainer Smith, Walter M. Miller Jr., Gene Wolfe, John C. Wright and of course CS Lewis are some really great exceptions that incorporate their belief wonderfully into their work if you want to ever give it another shot.

Bingo.
Heinlein was a very talented writer.
He was simply wrong about a great many things.
The author of this piece catches a lot of things, and he is wrong about a lot of things.
Starship Troopers authoritarian? Far less than socialist regimes today.
I found the bit about Heinleins peculiar sex life to explain much of his stunted worldview on sex, and perhaps why he never had children.
You might try some John Ringo if you think that all SF is Godless. Baen Publishing has a few of his on their Free Library. Try Gust Front, which is a free download in whatever ebook format you prefer.
