Earlier quoted context omitted.
I get what you're saying, but your tone here is pretty hostile here and you don't seem to acknowledge that the point you're making is in perfect agreement with the post you're responding to. You quoted him just before he said, "[This] is, of course, nonsense."
Did he edit his comment after you replied? I totally agree with what he said to GP: "don't include me in your 'we think war machines are cool.'" That's bad form in general, doubly so on this touchy subject.
I think so.
The same factors that make machines cool remain intact regardless of the application. Furthermore, there's much more kinetic energy involved when you're trying to take something apart quickly than when you're trying to carefully build it, and more still when someone else is trying to keep the thing intact. Is a controlled demolition cool? If not, why do people watch?
Nobody is arguing in favor of violence. The comments here are recognizing some of the reasons why war seems cool, especially to the young and especially to men.
