G - Your point is well taken. When I was going through the interpretation of the cards, I didn't really think anyone was going to assume that I was stating facts just because I had used sentences with "is." (And from the feedback I've received, that's been the usual case - people have been able to read the book as an exploration of the authors immagination). This is more of a writing style than anything else. I'm sorry if this threw you off, but I think the verbage was used as an extention of the premise, "within the context of this Cathar-tarot connection, this IS how I see it." Sorry if that caused some confusion.
I think that most books which deal in subjects that revolve around unproovable topics can always be picked apart, and my book is no different. What I've tried to offer is something new to the discussion.
In general, people want to accept things that agree with what they already believe, and reject those that don't. This is just human nature. You said yourself that having to accept the fact of the Judgment card still troubles you. This shows the inherent resistence we all have to ideas which don't conform to our own. And this is likely why the greatest resistence of this theory has come from people who have preconcieved ideas of what the tarot is all about. I'm not trying to say that you're stuck on any particular theory - as you have previously made this clear - but this is the general response I've noticed. The book was not written to make the statement, "this is how it is," but rather, "this is how it could have been." Fortuantely, most people have been able to make the distinction.
The fact that some interpretations are only applicable to a particular deck introduces a potential problem, as you pointed out - not all the decks share the same imagery. Of course, two things are possible: 1) that only the images that all the various decks have in common should be considered valid, or 2) that various decks were altered or made slightly different due to the personal (religious, political, etc.) perspective of the artist... or 3) that none of the variations mean anything in particular, but are simply the result of random artistic expression. I'm assuming that the second case is true.
