I would suggest that it's a dead end without a mutually agreed upon philosophical framework to contain it. The participants in a debate are unlikely interested in agreeing to one particular framework, and this is a big part of why critical theory in other areas is such a hot-button issue: the philosophical presuppositions that critical [X] theorists want you to make are inconsistent with the worldviews of some other people (and even inconsistent with other critical theories in some instances).
