I'm simply criticizing a person who took a completely inflexible and dogmatic position, namely that "A person operating a moving vehicle should have 100% of their attention focused on the road." And further stated that all arguments otherwise were simply attempts to rationalize unsafe behavior. All I'm doing is pointing out that this implies that arguing you should be able to e.g. turn on your headlights is "rationalizing unsafe behavior" according to that metric.
