Further, this entire line of discussion is nothing more than a       meaningless digression. By now you should understand what I meant and       the only further discussion beyond this post on my part of other ways of       interpreting it will be to call you out on using the digression as a       smokescreen and to accept your concession of the point.              >> Making an absolute statement that is then clarified with a caveat is a       >> common rhetorical flourish. Furthermore, saying that something       >> "doesn't really exist," isn't actually an absolute statement of       >> non-existence.       >       > Rhetoric is often little more than politically convenient, socially       > acceptabe lies. It is a tool for those who can not debate honestly.              I was using the term in the sense of the use of language to persuade or       communicate. Not that you complaining about a word choice there is       anything but a pointless digression that will, at best, head out into       more semantic quibbling.              >> Leaving aside that this would just be part of the military budget and       >> not something that the general populace would ever see broken out as       >> its own line item....       >       > Military budgets are not infinite.

What's more, it's a post that you       clearly read because you used information from it.              >> The costs of this sort of system is going to be peanuts next to the       >> cost of the warships, (whatever form they end up taking).       >       > I think that I have already mentioned that "peanuts" can prevent a       > warship from receiving funding.
