The other reason for single sex toilets, of course (other than safeguarding), is that this is what the students overwhelmingly want. Whenever kids are asked, they say they want single sex toilets.
Apparently if a child wants to cut their breasts off and take experimental drugs, they have agency, but simply wanting privacy, dignity and safety (both girls and boys)? Nah, fuck off kids.
Bringing in 'gender neutral / mixed sex' toilets is quite clearly the imposition of an adult ideology. It's evil and anyone not standing up to it is complicit.
Children only are 'competent' and have 'agency' when it feeds into the adult ideology. If their opinions don't agree with the adult ideology, their wants and needs apparently don't matter.
Safeguarding red flag.
