I would say about 75% of the letters published in the hard-copy version of the ST are sent in by petty, stupid, whiny people. I think the ST is a piece of crap newspaper to begin with anyway.
As much as I would like to think that the ST editors are having a good laugh at these people who send in these stupid letters, and publishing these letters so that we can have a good laugh at them, I don't think the paper is intelligent enough to do that.
It's just a bad newspaper, period.
Look at it this way: this letter has sparked lots of debate here and elsewhere, and people waste their energy on petty items instead of maybe pondering some more important and less convenient questions. Mission accomplished.
