Janice, it would be interesting to track down the origin of the phrase. I suspect with David that it originated amongst leftist and human rights activists, however much it was later taken over (as Janet mentions) by the Murdoch left-baiting media. I'm reading currently Alan Gould's fiction "Decency and Honour" from The Enduring Disguises (for the Seventh Chimaera's Gould feature). It evokes that whole late-60s political activism scene (in this case amongst students in Canberra) that gave rise to such attitudes. Highly recommended: it's a wonderful jolt of memory, and nice satire, and more. So many of the old phrases that had sunk into time. (I'm also re-reading the Four Fabulous Furry Freak Brothers and Feds 'N' Heads, which similarly bring that era back to life -- in a different kind of way.)
