You seem to be making an assumption. FTR, you can be neither a doom-monger nor a happy-clapper. But go ahead and throw false dichotomies into the mix while you're at it.
But getting back to your 'argument', if there's nothing wrong with looking coldly at what, as far as you can percieve, seem to be the facts of the matter, then there's nothing wrong with looking at them warmly either. Given you've already admitted you're only arguing about perceptions of facts rather than actual ones, surely both hypotheses are equally valid/invalid/delete as applicable?
