Sweden has been raising kids in a more gender neutral environment for quite some time. Meaning they don't really assign and constrict what kids can play with based on sex. Girls play with dump trucks and boys with dolls and it's not frowned upon.
How are they supposed to explain reproduction and sex to these kids? As much as I want to sympathize with the overall principles that these loose canon parents are trying to teach, it's just a matter of fact that children are born one sex or the other. Is sexuality and sexual identity that removed from biology?
