Racism and Tolkien.

[Lalaith]

Tolkien was a specialist in North European languages and literary traditions so it is natural that his work would have a North European 'feel' in terms of the culture and appearance of his heroes. That doesn't make him racist.
I would also, like Inderjit, point to the Druedain, who are about as non-Aryan as they come.
Not only are they held in enormous respect and affection by both elves and their fellow Edain, but they are also the only men *never* to have succumbed to Morgoth.
