(Meta-discourse note: some time after writing the parent, I worried that I had worded it far too harshly. I usually try to keep most of my comments here very close to being emotionally neutral, on the grounds it's better to err on the side of being Spock-like than to risk letting my passion tempt me into saying something obviously wrong or harmful (which has happened a few times). But given the karma count and lack of disapproving replies to the parent, perhaps I didn't actually do so poorly by making an exception this time? Maybe I should even update a little bit in the direction of thinking that it's okay to express emotion sometimes, as long as you clearly explain what you're doing? I'm not sure.)

[Edited to add: Actually, I still feel guilty about being non-nice, so I've edited out the two instances of cusswords, which, while entertaining, didn't actually add any substantive content.]
