Sometimes I am not sure why I bother getting up in the morning.
Joshua had made this comment "Dinosaurs never turned into birds, birds existed at the same time they did."
Now that is an incorrect statement and we know this to be the case. Birds are, cladistically, dinosaurs. My challenge to Joshua was to mimic the argument used by YECs and the like when we talk of most geological evidence. It was a gentle mocking, or - if you think I have some hidden agenda - a snide, patronising mocking.
I recognized the quotation marks and understood it as you describe it. However, I could not let it be hanging in the air.

My comment was not directed towards you but for any YEC reading it.
Regarding Joshua's comment that birds existed at the same time as dinosaurs, I believe I made a comment about this; it is a logical necessity birds existed with dinosaurs since birds are dinosaurs.
On thew other hand, I think I know what it is Joshua is fishing for with his comment, and if so, then in his definition of bird he must include dinosaurs with teeth, tail and clawed fingers as "birds" - but only then to make what he think is a "bird" even more dinosaurs-like.
Creatonists seams not to understand or refuse to accept what classification is about. It seams like they somehow reason there is a particular instance of a special species named "bird" and "dinosaurs", and that the this special "dinosaur" somehow stopped being a dinosaur and then changed into something else called "bird". But this is not how evolution works. YEC also acknowledge that this is not how evolution works when they say "dogs only make more dogs". I agree, and mammals only make more mammals. Dogs is one particular variety of mammals to make more mammals. In the same way birds is one particular variety of dinosaurs to make more dinosaurs.
Put in other words, all birds make more dinosaurs, but not all dinosaurs makes more birds - in particular the extinct dinosaurs. That means you are all the modification what you ancestor ever been and you can never escape that. There is no such things as evolving from one kind to another kind. Everything is a modification of the same kind. Everything is the same kind.
It is a puzzle to me how people can accept whales, rabbits, and bats all being mammals but not birds being dinosaurs. Maybe it is because YEC invested so much prestige in denying that birds are dinosaurs they simply cannot admit it anymore without losing that prestige. It seams to me they reason is like this; if YEC admit birds are dinosaurs then they must accept the nesting as evidence for common decent which then will have a domino effect and imply that all mammals also have a common ancestor (implying humans and chimpanzees also shares a common ancestor). And for religious doctrine reasons this cannot simply be accepted. If this is the case, then in a sense religion makes you dumb.
