I have a three word horror story for you...single sex schools! Thats right such schools do exist. For every straight person that is their worst nightmare. Which leaves the question; Is it a better learning environment? In short the answer is no. Interaction between genders is far too critical in our social skills. It also makes it hard for any gender that is not cist-male or cist-female. Does it save money? No due to having to have twice as many staff and facilities than if they were shared. So why are we endorsing single sex schools? Because some parents and guardians want their child to grow up sheltered from the harsh realities of life.
