I've seen the churches you talk about, and I would almost call them "progressive-fundamentalist". The hallmark of fundamentalism isn't really adhering strictly to the text (after all, the text is so multifaceted that there's not even just one definition of "strict adherence", despite what they would tell you). The defining trait is turning the text into a battle-cry instead of an invitation for contemplation and love and self- and community-work. Progressives are just as likely to do this as conservatives.
