What really gets me is that all this was provoked by an on-the-balance respectful, and complimentary comment - th at included a comparatively minor criticism.
If you want an example of an attack obit, there is the famous Mencken obituary for William Jennings Bryan
I'm not going to forward the whole thing. but here is the link http://www.peeniewallie.com/2005/06/h_l_menckens_ob.html
And here is a taste:
======================================
It was plain to everyone, when Bryan came to Dayton, that his great days were behind him -- that he was now definitely an old man, and headed at last for silence. There was a vague, unpleasant manginess about his appearance; he somehow seemed dirty, though a close glance showed him carefully shaved, and clad in immaculate linen. All the hair was gone from the dome of his head, and it had begun to fall out, too, behind his ears, like that of the late Samuel Gompers. The old resonance had departed from his voice: what was once a bugle blast had become reedy and quavering. Who knows that, like Demosthenes, he had a lisp? In his prime, under the magic of his eloquence, no one noticed it. But when he spoke at Dayton it was always audible.
When I first encountered him, on the sidewalk in front of the Hicks brothers law office, the trial was yet to begin, and so he was still expansive and amiable. I had printed in the Nation, a week or so before, an article arguing that the anti-evolution law, whatever its unwisdom, was at least constitutional -- that policing school teachers was certainly not putting down free speech. The old boy professed to be delighted with the argument, and gave the gaping bystanders to understand that I was a talented publicist. In turn I admired the curious shirt he wore -- sleeveless and with the neck cut very low. We parted in the manner of two Spanish ambassadors.
But that was the last touch of affability that I was destined to see in Bryan. The next day the battle joined and his face became hard. By the end of the first week he was simply a walking malignancy. Hour by hour he grew more bitter. What the Christian Scientists call malicious animal magnetism seemed to radiate from him like heat from a stove. From my place in the court-room, standing upon a table, I looked directly down upon him, sweating horribly and pumping his palm-leaf fan. His eyes fascinated me: I watched them all day long. They were blazing points of hatred. They glittered like occult and sinister gems. Now and then they wandered to me, and I got my share. It was like coming under fire.
What was behind that consuming hatred? At first I thought that it was mere evangelical passion. Evangelical Christianity, as everyone knows, is founded upon hate, as the Christianity of Christ was founded upon love. But even evangelical Christians occasionally loose their belts and belch amicably; I have known some who, off duty, were very benignant. In that very courtroom, indeed, were some of them -- for example, old Ben McKenzie, Nestor of the Dayton bar, who sat beside Bryan. Ben was full of good humor. He made jokes with Darrow. But Bryan only glared.
One day it dawned on me that Bryan, after all, was an evangelical Christian only by sort of afterthought -- that his career in this world, and the glories thereof, had actually come to an end before he ever began whooping for Genesis. So I came to this conclusion: that what really moved him was a lust for revenge. The men of the cities had destroyed him and made a mock of him; now he would lead the yokels against them. Various facts clicked into the theory, and I hold it still. The hatred in the old man's burning eyes was not for the enemies of God; it was for the enemies of Bryan.
