I think there can be a difference between facts and truth. I also think that there are objective or non-conditional truths - myths can be true in this sense though not factual. I believe, I'm almost certain, we disagree on both statements.

We might agree that myths are useful to some.
One of the problems I find on the FR, especially on the Religion Forum, is that people make up word meanings the way they make up their beliefs. It is no wonder that we tend to talk past each other.

Now, if we are going to make up our own meanings then the whole point of any discussion meaningless, which is becoming apparent more and more every day on these threads.
