I agree with everything you said DGS49 except the part about when your son died it wouldn't be your sacrifice. It most certainly would be.
Khan didn't sacrifice anything, he LOST his son who sacrificed his own life. His son is a hero and true American. Khan is a grieving parent who lost a son. Khan became a fair open target once he stepped on that stage and started playing politics. His son will never be an open target but a hero.
