I know that I, personally, deleted all replies to a post I deleted (does that make sense? ;)) for a few reasons. First off, since the original point is gone, the member replying sort of look like an idiot replying to something that wasn't said. Also, the person who posted the original deleted post would know you were talking to them, so they'd reply to
you, and the argument rolls on.
