I'm not for any type of fighting in a battle. As I said in another post, if someone says something you have problem with catch them after the battle or end the battle at that moment. Don't mess up things for that league or venue. And once you throw a punch who knows what can get popping.
Battle rap can be weird sometimes: you can say whatever you want about their mom, wife, sister, daughter, or son but if a white guy says nikka then something has to be done. I have other thoughts about that word, but that's a discussion for another time.
