Let's summarize Basketcase's logic by considering the following sentence: Basketcase is a transvestite.
What do we know about that sentence?:
-- There is no evidence that conclusively proves that it's true.
-- But it's possible. We certainly have no evidence that would allow us to say as an absolute fact that it's untrue.
Thus, according to Basketcase, the statement that "Basketcase is a transvestite" must be accepted as an honest statement of fact.
From now on, we'll start referring to Basketcase as Caitlyn.
