Girls-only schools should be a thing again

The title speaks for itself. I don't know whether they are around in the US, but in most parts of Europe they are gone. That's a shame, since several studies show that women who went to all-girls schools were more likely to be academically successful and confident. Plus it's much safer to be in one since boys are, due to their delayed maturity levels at that age, more likely to clown around during classes and make trouble in general. And it's much easier for girls to get into usually male-dominated subjects like math and physics when there's no competition/tension among the genders in that space. In this instance I remember when I took a P.E as an optional course in school when I was 15 because I liked to play sports, but turned out I was the only female in the course and couldn't really do anything in classes due to the fact that I felt super uncomfortable + I would've put myself in danger if I tried to play e.g football with people almost twice my height and strength level. I know sports are kind of obvious, but the same kind of tension can be applied to other subjects imo. In general I personally had to endure a lot of shit from little spermoids in school when I was growing up, and now as an adult I genuinely feel like I would've turned out way more stable if I was surrounded only by girls. Boys could also benefit from gendered education, since they could learn at their own pace and girls won't have to put up with people who act like preschoolers.
