As Brewdabier says, it depends. In some states you practically have a duty to submit to your attacker. In a state like Texas, your rights to self defense are much broader.

If you're familiar with the name Soros, he's spent hundreds of millions of dollars supporting communists running for District Attorney, so they can undermine self defense from leftist attackers. Anyone with the possibility of a self defense situation should KNOW their local laws, and also know the position of their local prosecutors. Even in a good state, you might have a soros puppet who won their election.
