from what I gather, usually they argue against the literalist view, which every work for the toll houses says you can't do. it's usually one big straw man.
From what I understand there's two different camps within the Pro-Tollhouse movement: the literalists and then those who take a more metaphorical/figurative understanding. When I argue against them it's the literalist view I'm arguing against. I don't even take issue with the metaphorical understanding, especially since I don't entirely reject the metaphorical understanding.
