Many states (15) have a duty to retreat, not everywhere is a stand your ground state (35 states). It's complicated, but most of the time in your home there is an exception.
I specified that the perp is both facing me and in my home (as opposed to my possibly 1000 acre lot - I wish). This scenario is legitimate self defense in all 50 states (unlike some states in Europe)
They specifically mentioned a scenario where someone is trespassing into the home. There isn't a single state that has a duty to retreat requirement that pertains to home invaders.
