I don't think Harris would claim he's making philosophical arguments aimed at philosophers. I think he would say he's making arguments against beliefs that most people (non-philosopher) hold. Most people who show up to church don't claim that they worship a god who just so happens to not be good. They believe in a god is perfectly good, who takes an interest in their personal lives and will decide the subjective nature of their experience after death.
