Therefore, I find your characterization of it as "an ass" to be cynical, self-serving, and pointless

Not my characterisation. I don't mind being likened to Charles Dickens but doubt very much if I ever will achieve his fame. Cynical? Maybe, but true. Self-serving? If you mean it was used to underline a point then, yes, I suppose so. Is that supposed to be a bad thing? Pointelss? As pointless as starving a child to death in the name of god? Maybe, but it does less harm.

As to blowing off steam. Not at all; just stating my opinion. I would not get annoyed over anyones mental condition. Unless they told me that I had to take notice of their imaginary friends as well:-)
