The immediate aftermath of someone's death is not the time to critique them, gently or not. Total lack of decorum and social sense. Not fit to teach young children.

Very interesting. I stand corrected. I will note, however, that this is literally the only example I've seen of someone getting fired for a legitimately non-celebratory remark. We've got a legal system for stuff like that. For every single example you could give me, I can give you at least a thousand counterexamples. 99.9% of all the folks being fired are getting fired for being reprehensible.
