I accept that some girls may grow up being taught that trans girls are predators and are men they should be afraid of and absolutely under any condition should not be acknowledged as girls. I accept other girls may grow up learning that trans girls are girls, belong and should be included as girls as they will grow up as any other girl to be women.
I accept each group of girls could be encouraged to accept their environment or fight against the status quo. I imagine that adult influence would also have a massive influence positively or negatively on how a girl would feel in such a situation.
Her feelings are very real and should be heard. Resolution, if needed would take place within the rules and culture of the school. Just as any other feelings about situations would require.
