So....with that perspective in mind, my opinion is: if someone is trying to seriously hurt me, I'd use anything in my power -- my legs, feet, arms, anything -- to defend myself. I'd worry about the consequences later. Call me arrogant, but I stand by my choice.
Good for you. You're not arrogant for refusing to be a victim. If your attacker gets hurt they brought it upon themselves by being a bully and an assailant.
