if the "hard evidence" is really that birds come from [in whatever complicated and inexplicable gradualistic pathway]dinos it strikes me as strange that there are evolutionary avian experts who reject such interpretation.

It is not inexplicable. Current gaps in understanding or evidence (which are forever closing, thanks to hard-working people who are curious and like to explore with eyes open, unlike you) mean that the full explanation may be deferred for now. That is not the same thing as the defeatist "inexplicable." And no bloody Gods of Gaps, please.

telling me that something is hard evidence tells me little more than what you believe or accept, since the creationist can do just the same.they have the same evidence to interpret as the darwinist.

Of course, but you won't look at that evidence, will you, let alone "interpret" it (aka, in your case, reject it out of hand and take the piss out of scientists, as ever). You can but you won't. Evidence scares you lot. Have you read "Origin" yet, for example? And stop saying "dino." Go and kick your own arse for doing that.

"Evolutionary avian experts" is rock-solid weasel words, by the way. Name names and describe their views that give you so much comfort.
