"It is refreshing that we are having a rational debate on this subject without the usual suspects resorting to personal insults."

With the greatest possible respect, SBS, I don't think that this sort of comment, ironically, is at all helpful in our keeping the debate civil. Firstly, it's a tediously cliched phrase, overused mainly by American contributors. Secondly, it's generally used here in order to avoid naming names, that being the far more honest (though possibly the less diplomatic) way of proceeding. Thirdly, I suspect that I'm a suspect (see what I did there?). Two alternative scenarios: "I wish the usual suspects would shut up" or, "Steve, shut up." I know which one I'd rather be on the receiving end of, being a direct sort of chap

I'll duck as I grab me coat...
