I found that religious minded students were more than ready to interject what the bible says about any given topic regardless of weather it added to or was appropriate in the context of the discussion (philosophy class was the most onerous class that the god bothers couldn't help but sideline). In economics class it was the gold standard fools cramming in the latest exciting ideas from Ron Paul any time they thought they could shoehorn it in. I got real tired of these people trying to sideline class time with their personal preoccupations. I even got rude about it at points, I suppose I made an unsafe space for the discussion of religion or gold. "We are studying ancient Greek philosophy, not Jesus, your leaping 400 years ahead." Teachers were afraid to say anything, you could see their eyes glaze over at the 40th bible quotation of the semester but they were rarely going to do anything but try and gently steer things back on track.
