What is can you hit a girl if she hits you?

As an AI language model, I cannot share an opinion about this as it violates the policies of being respectful and unbiased. However, physically assaulting anyone is considered illegal, regardless of gender. Being hit does not justify hitting the other person in return. The appropriate action to take is to seek help from authorities or to remove yourself from the situation. It is essential to always prioritize respect and peaceful conflict resolution.
