Some of these things are exist in every society and every school and the best thing would be to homeschool your child for the first 10 years.
I am totally against the sex-ed given in UK and US schools, but in Pakistan there is NO sex-ed at all which is also wrong.
I remember how girls in my school in Pakistan outcast shia and wahabi girls. And not to mention how girls went on dates by bunking school. In the end, it comes down the parents and how they train their children.
One thing I like in Pak is family life…people aren’t workaholics and hence more relaxed.
