Exactly. Gary DeMar has absolutely no foundation upon which to make his argument against dispensationalists (even ignoring the fact that his arguments about Greek demonstrative pronouns are not sound in the least). DeMar's eschatology, and Reformed eschatology in general, are based upon a completely figurative and exceptionalist approach to Biblical interpretation - in essence they twist the Scriptures to force them to fit into a historicist mold. The way DeMar and other anti-dispensationalists approach the Scriptures essentially turns the Word of God into a "choose-your-own-adventure" book like the ones we read as kids.
I see it's easier to throw stones than address the substanmce behind the charges. E.g.,
How will we ever convince skeptics of the truthfulness of the Bible when it is distorted to defend interpretations where "this" means "that," and "this is that" actually means "this is like that"?
Thus the true state of dispensationalism and it's fundational methodology is revealed.
