There does not need to be an alternative because you are wrong; calling someone a nigger is not provocation.
I know that's what you want. You want calling someone a nigger to be classed as provocation, a sufficient reason to strip someone of their right to self defense. Because they are your god, and it's blasphemy to insult your god, and the punishment for blasphemy is death.
Yes that is exactly the argument.
Under the law you have the right to defend yourself from an attack.
But if you provoked the attack, then you lose that right to self defense.
That leaves you with two options.
1. Do not defended yourself, in which case you can just die. Your life is gone.
2. Defend yourself and go to prison. Your life is gone.
That's all there is to it. Death for Dalit who offended the Brahmin.
