Does being an atheist make you closed minded?

It's often assumed that people who don't believe in supernatural entities like gods and ghosts are closed minded. However, you can except the possibility of something being true without believing in it. How is that closed minded?
Here's a video I made a while ago in which I argue that being an atheist does not make you closed minded.

Possibly creationism's best ever attempt to explain feathered dinosaurs

Almost every creationist argument is based on the assumption that Genesis is an account of actual events, and that the bible is the word of God and therefore the only truth. This is one of the main reasons why all their attempts at science have failed, because they only look for 'evidence' which is remotely compatible with their own assumptions. Alternatively they look for 'evidence' (a term we should use very loosely in this case) that contradicts their own grotesque caricature of the theory of evolution, often based on misunderstanding, deliberate misinformation, and complete ignorance of reality.

The idea of dinosaurs with plumage has often ruffled the feathers of the creationist movement. They've never really tried to explain why dinosaurs have feathers at all. All previous attempts by creationists to explain can be summarised by at least one of these points :

• In Genesis- birds were made on the 5th day, but God filled the land with animals on the 6th so birds must have come before dinosaurs. Look, it's in the Bible - which is the word of God because it says so in the Bible- therefore it's true.
• When I don't inspect it closely, it looks more like a bird than a dinosaur. It's a bird.
• Evolution is only a theory.
• I don't know much about the natural world at all.

 However, after searching through answersingenesis.org I finally found an attempt at an explanation that tickled me.
Dinosaurs ate Birds. Birds have feathers. Dinosaurs therefore ate feathers. If you completely ignore every piece of scientific evidence which suggests that dinosaurs had feathers and completely ignore the context in which these these sort of observations should be made- it makes perfect sense.

If you want to know more about evolution, two books I'd highly recommend are Evolution: What the Fossils Say and Why It Matters and Why Evolution Is True.
