Racism in LOTR?

Tolkein wrote "The Lord of the Rings" and his other works because of one reason. Tolkein was British and mourned the fact that any trace of British mythology was wiped out by the Saxtons when they invaded Britain. He wrote his works to replace those myths and legends that were lost. He did not have any apparent racial prejudices, he was just trying to convey what Britain's point of view was at that time into "Lord of the Rings" and his other books and letters.
