I can surely speak for myself. Considering zarny's (wildly similar and dismissive) post in the *American Idol* thread, I have a hunch he or she (I have no interest which) likes to say how 'stupid' things are. Have at it. Seems to me said 'poster' is only "qualifying" themselves.
And won't be around long to worry much about.
