I have no problems with quotation-marks used to denote sarcasm, questioning validity, or academic curiousity (the first three categories described in the linked article), because they all communicate the same thing: "I'm deploying this word because it's well-recognised, but it might or might not be the word I personally would choose". The fourth category in the article, quotation-marks for simple emphasis, really irritates me because it's the exact opposite of the above: endorsement of the quoted words, rather than dissociation.
