It's not possible or it's not preferable to you? Your preferences are your own and it absolutely is possible to keep arguing back and forth in the same post. Moreover, after a few comments, the viewer has to click a link to even see the rest, so that everyone else doesn't have to suffer fools. Let me clear things up: You think that your argument has a higher value for some reason and thus it's necessary to create not only a new post, but a whole goddamned new sub for it too... You are not special and nobody gives a fuck.
