 Their comfort level in the bathroom depends on who else is allowed to use it. Most girls feel comfortable using the girls' restroom because there will only be girls inside it. These girls will not feel comfortable if anyone else, if anyone else who feels comfortable, regardless of sex, is allowed to join them. The upshot is that normal girls with a normal desire for privacy and safety will not feel comfortable anywhere now in Chicago public schools. There's no restroom for them to use.
