True kinda, but that's also a convenient caricature, one that binds the right to the muscular left. The praxis starts with a recognition that power relationships are revealed and transmitted through language, something I know you recognize. It did go off in all sorts of crazy directions--e.g., Antioch--but the kernel of it was rational.
