Stupid angry letters from ignorant people are an excellent source of vitamins
And by "vitamins" I mean, "topics to write about."
I had a very good university professor who shared opinion pieces and rants to the editor which were full of flaws - usually due the fact that the people submitting the articles did not have a clue about what they were talking about.
After we saw one particularly egregious example, I asked if he considered writing a letter to the editor pointing out the mistakes.
The answer was no, "life's too short."
And once you're a professor with tenure, flying to your country's capital on a weekly basis to testify before Senate committees on This Important Topic and That Giant Failure Committee, it makes sense.
As a student, I had time to complain, and writing poured forth.
These days I'm starting to pick my battles more, but sometimes you'll see that completely insane rant that screams to you, "this is stupid, and the many levels of "wrong" must be exposed with the burning light of knowledge and wisdom."
Kind of the like the Bat of Knowledge and the "You will learn" catchphrase from this site.
I've decided it makes sense, in terms of writing style, it makes sense to separate the introductory rant from the intelligent arguments, so look forward to an electrifying part two, where the failure is exposed in a cascade of knowledge.
