Things for which there is no evidence...

[Fidel_Castronaut]

I think when we say that as atheists, that it's possible to believe in other "supernatural" things while not believing in a god, comes down to a response to theists.

Often times we're hit with, "Oh, you're an atheist, so you don't believe in <insert concept here> either."
It's just a response to show that aliens, ghosts, dragons, whatever, etc, has nothing to do with atheism. Atheism means you don't believe in a deity, nothing more. This is just to prevent them from adding more meaning to the word that isn't there.

Exactly.

Whilst it may indeed be true that you'd be hard pushed to find an atheist who believes in dragons, this is entirely irrelevant to being an atheist. Indeed, if no atheists believed in a dragon of any sort, this would not be because they are atheists. It would be because they have applied the same reasoning to why they disbelieve in claims of deities to that of dragons.

This sort of fallacious reasoning gets more insidious when terms like 'secularism' are thrown into the equation. A lot of people purposefully distort the word secular to become almost synonymous with atheism, when really it's nothing of the sort, and bares no relevance whatsoever.

Again, whilst it may indeed be true that all atheists are also secularists, it doesn't thus mean that all secularists are atheists.
