[Despanan]

Basically was an old upper-class british guy, and thus what he wrote subconsciously extolled his beliefs and virtues. Because he was so influential on fantasy - most of these beliefs have become tropes in nearly all standard fantasy stories.

It's not that Tolkien's beliefs were necessarily BAD, just that they were problematic because of his limited experience, and this means alot of standard fantasy tropes - like seeing race as an indicator of behavior and personality - are also problematic.
