The school administration did nothing for her and they’ll do even less than nothing for kids in this club that get bullied by religious students.
I think part of the purpose of the club is to create a sense of shared identity and form a collective defense mechanism against bullying by aggressive students and administrators.
Of course, this gives the administration one big target to smash rather than a bunch of little targets. But that’s the nature of organizing in defiance of a violent and oppressive authority.
