Why do schools punish someone in a fight who is defending themself?

Are people really expected to let themselves get beaten and suffer possible severe injuries instead of protecting themselves?

My granddaugher age 9 just got supended from school. She kept telling the teacher, teacher did nothing. So my daughter went to school and rasied hell. Still nothing, So I told my grand daughter to beat the shit out that little punk if he kept on hitting her.

She went after him like a windmill in tornado and beat the hell out of the kid that kept hitting her since school started. She gave that bully a black eye and a fat lip

Now she the one in trouble, but I bet that kid will never pick on
