Many of those I'd write off to Tolkien being a product of his times. At least his heroes seemed to have many ideals which are still accounted virtuous.

Tolkien's monarchism, though - even in the days of the Old Testament, it was obvious that hereditary monarchy never, ever worked for long. Because the heirs of great men always regressed to the mean. Pretty damn fast. (After King George III, Britain mostly solved that problem by turning their hereditary monarchs into mostly-symbolic figureheads.) And Tolkien served in the hellish trenches of WWI - a war which dug deep, dark graves for both hereditary monarchy and European superiority.

Hmm...in many ways, I could argue that Tolkien's fantasy writings were mostly escapism for him - to a old-fashioned romantic utopia, where "land of milk and honey, and the kingdom is powerful and prosperous, and the king is always good" was at least possible. And consider the massive decline in the real Britain's fortunes between Tolkien boyhood (~1900), and LOTR's publication (~1955)...
