Remainder below the cut to spare those not terribly interested in politics.
I note that this discussion came about less than a week after the chickenhawk argument broke out again thanks to Atrios, who caught flak from (among others) Blackfive and Reverend Sensing of One Hand Clapping. Tigerhawk made the point that Atrios was essentially buying into the argument underlying the society Heinlein described in Starship Troopers, namely, that nobody besides veterans deserved a voice in how the government is run or what policies it follows. Pretty weird argument for a lefty; most folks on that side of the political fence in fandom usually condemned Heinlein as a fascist for that book, after making the classic critical error of conflating the author's views with those of his characters.
I've had the "chickenhawk" argument thrown in my face before, and it tells me that I'm not dealing with someone interested in a serious discussion of the issues, because as Christopher Hitchens pointed out, it's an absurd argument that has no logical underpinning whatsoever. The fact that's it's being trotted out again as a way of "shaming" pro-war conservatives doesn't make it any more logical or convincing.
