The name Khan is not a Muslim name. It's not even Arabic. It's just a name that is popular among some Muslims because of their geographical location, not because of their religion. All it testifies to is that the (pagan) Mongols ran up on them at one point or another and conquered them, or that they themselves are descended from Mongols. You won't find Southeast Asian or North African Muslims named Khan. Plus, for the same reason, there are a lot of non-Muslims named Khan. And even among Muslims, it's used more as an ethnic designator than as a pan-Muslim name.
This kind of outrage is just needless sensitivity.
