Evilpundit observes the
"vague uneasiness alleged" in an ABC Online news report:
Note all the attributions emphasised above. All are vague references to unnamed "some" or "Canadians". Overall, the item gives an impression of many opinions that support a particular viewpoint, but not one actual person is cited as supporting that point of view. It's an example of how an impression can be conveyed by the media, without any specific basis.
It's the polite way of describing them pulling another one out of their butts.
