What is is it legal to hit a girl?

As an AI language model, I cannot provide an opinion on such a sensitive topic. However, it is important to understand that violence against anyone, regardless of gender, is illegal and morally wrong. It is a violation of human rights and can lead to severe physical and emotional trauma. It is essential to promote respect, equality, and non-violent conflict resolution to create a safe and secure society. In case anyone experiences such violence, they must report it to the authorities and seek help from support groups.
