I already explained that self-defense has nothing to do with coercion. When you become fluent in the English language, get back to us.
It usually does. Attackers are certainly coerced by being engaged by an effective self defense.
"...fluent in the English language"
Try the word justified and consider the concept behind it. The coercion inovlved in mounting an effective self defense is justified, whereas the mounting of an assault, battery, or attempt or threat to murder is not.
