Indeed. Far too many people lump all Muslims together in one group. Some know just enough to realize that there is a difference between Sunni and Shi'a groups and the smaller sects like the Ibadi. A few might even know that there is also a difference between Islamist fundamentalists from various groups. Fewer still know that bin Laden is a Wahhabist (Salafi), which is one of the fundamentalist Sunni groups, and is not in any way associated with the fundamentalist Shi'a groups. It's like lumping all Christians together without taking the time to distinguish between Roman Catholics, various Orthodox groups, various Protestant groups and others like the Jesus Christ Church of Later Day Saints otherwise known as the Mormons.
