content: There's been an effective defense for centuries. Around blacks, never relax. Failing that, I'm sure if you went for the throat it could be argued as self-defense. After all, if you're grabbed by the hair, you have every reason to believe it's so your head can be smashed against something; be that a wall, the ground, a knee, etc. All of those can easily kill you. So if a sheboon grabs your hair, you grab its throat and don't let go.
