Um, you do really believe there are Faeries, I take it.
Okay.
I admit to having played with the notion in days gone by, but never gave it actual credence, as such.
Such a belief most definitely will affect how one views Tolkien's work. It would, I suppose, be on a par with, in my case, someone, say, a J.R.R. Van Essendelft, writing an entire Legendarium that adds to the New Testament in ways that are not exactly according to accepted doctrine, but actually beautifies it in profound (and therefore) troubling ways. Is this how you see Tolkien?
