Maybe it isn't about what's being taught, but acknowledging that boys will behave differently when girls are present. So then an environment where no girls are present can be an opportunity to engage with teenage boys in a different context, which I do think is important to provide some kind of mentorship or guidance that isn't possible in a mixed environment. There aren't many situations where this is still the case, and getting rid of all such opportunities for the sake of inclusivity might be missing the point, and do more damage than good.
