Punctuation as a weapon : or, the inverted comma rampant

I've been becoming increasingly conscious recently of the use of language to make a point. I don't just mean the actual words used, but their context. Anyone with an Internet connection can broadcast their views to the world at the press of a button. I'm all for free speech, of course, but I'm not so keen on reading a lot of spitefulness.

One thing which seems to be happening quite a lot is the use of the inverted comma (quotation marks, sadly also known as "quotes" - ugh) to belittle and demean whichever group of people are the target of scorn. Thus, James Delingpole on public sector "workers" here and Tim Coates on the "profession" of librarianship here are trying to convey the ideas that people in the public sector do not actually do any work, librarians are not worthy of the adjective professional, &c.. Jacob Rees-Mogg's articles are chock-full of inverted commas, to the extent that it's quite difficult to see which bit of what he is saying you are not supposed to be taking at face value. (He sounds cheerful enough, though, so perhaps he isn't really having a go at anyone!). This blog by "categorically not the other one" captures his habit nicely.
Has the inverted comma become the weapon of choice in the blogosphere? Has it replaced terms such as "so-called"? I'd be interested in any other examples people come across - I've only mentioned a few which spring readily to mind, and I'm sure there are a lot more out there!
