Q: Why do non-fans think we think it's real?
A: If they have read some of the rants on this, and other, Trek forums... I can see how they could make that assumption. I have never seen fans of other fictional universes get so emotional and argumentative as Trek fanboys do over mundane minutiae.
Like any class of people, it is easy to stereotype the entire group by the actions of a radical few. It is not logical, but I have found it to be true.
