Idiocrosphere

Any thoughts or theories on this?

I'm not Mr. Online or anything, but over the course of a year or so I received fairly regular vitriolic, threatening, and/or generally hostile e-mail responses to a fanboy fiction story I wrote that was published online (I received more positive responses than negative, I might add). The story had a theme of race in it, which every "negative" response seemed to totally, utterly misread.

Is it possible that people who send these kind of violent, threatening cyber communications are, quite simply, fucking idiots?

I hope that's the case but somehow I think not.
