Apartheid works out well everywhere, doesn't it?
The more you divide, the more siloed you make a society. Be it on lines of sex, religion, social class or nationality, you create us and them narratives. People need to mix and separating children up because some representatives of one gender may be deemed dangerous to another is preposterous.
Also, this line was quite telling from the article.
Girls are more likely to be victims of sexual offences than boys, according to the analysis, which found that close to two-thirds of reported crimes affecting under-13s where the sex of the victim was documented had involved female victims.
So over a third of the victims were male. This isn't just a worrying statistic for girls but for all school-age children.
Questions of consent, what rape, sexual assault and sexual harassment are and misogyny (and misandry) need to be taught even from an early age.
