Children as young as 4 years old, learn about family structers and gender differences in school. Teachers do not ask for parents/guardians consent when it comes to teaching about this topic and nor do parents have control over this. 

A lot of parents have no idea what their child(ren) are being taught at school when their kids spend the 6hours/day for 5 days a week away from them. 

The ministry of education really needs to consider and respect parents/guardians beliefs and allow them to decide whether or not their child is allowed to participate in such topic. 

Some parents do not enroll their child in kindergarten because they're afraid of what the school system teaches.
