Be careful with this. In the US, the right to self defense is not universal. It's entirely dependent on the demographic characteristics of the people involved.
Cishet white male: unrestricted right to self-defense.
Cishet white female: provisional right to self-defense, usually if facing threat or murder, rape, or assault by a stranger. (If you know your attacker, self-defense does not apply.)
Everyone else: no right to self-defense exists. You will be prosecuted for assault or murder after unambiguous cases of self-defense. The one thing the United States will never accept is minority groups using lethal violence to protect themselves. Even most Democrats would be appalled by this. Deep down, most liberals feel minorities are supposed to be protected by benevolent white people; they're not supposed to defend themselves.
