I don't think warned people against marraige, he himself was a married Catholic.
People who say he was racist
are just wrong. He wanted
to create a mythology for England, 'cos they didn't really have
one of their own ( check
the facts, King Aurthur
is a Welsh legend before the English
nick him, Tolkien would have
been well aware of this). As such, It would have
been fairly hard to create a black/Asian charachter to fit an ancient/ near medievel english
Anyway, back to definition, he was a writer
who created the second highest
selling book ever ( the first being the Bible), and a very
good book it is too, the only people who say it's boring, are the ones who never read past the bit with Tom Bombadil.
