All I can say in response is generation nothing.
She's not a "little girl" in this case, ot. She's an assailant, who just happens to pee sitting down. No one's suggesting a curb stomp, but to defensively push or slap a violent female aggressor is totally reasonable. If she was one of the more threatening, butchy-type pugilists, well, unfortunately,
that bitch is going to sleep.
