What is an atheist as a basic type?

Atheists are bridge trolls.

Bridges are symbolic of passing over thresholds. When a person is moving from the Kingdom of Darkness into the Kingdom of Light they are crossing a threshold.

And lo and behold under that symbolic bridge resides the bridge troll, the atheist.

The atheist as bridge troll attempts to keep people from crossing over the bridge. The bridge troll atheist does this by attempting to intimidate; or to tempt (their weakest move because, after all, what does the atheist have that anybody could want?); or to mock.

Atheists are bridge trolls.
