Homeschooling children will interact with people in the context of their parents in all places in society their parents visit, and there are a wealth of groups and activities for the kids to join and interact with. Even better, the parents often have more direct insight into their childrens' interactions with others and can advise and support as necessary.

The whole 'needs socialising' claim is based on flawed assumptions, lest we assume all kids at school benefit socially from the environments they are in at school, which seems... optimistic.

Also, where else in society do you need to be measured in competence against other random local individuals of the exact same age?

How is that different from other children?

or with none or only other members of a religious cult and definitely not the kind of children the parent are biased against

the idea that a homeschooling kid from e.g. a very conservative christian family will have a less segregated experience is just funny

> same neighborhood

one of many many more reasons why neighborhood segregation is a huge problem (independent of weather it's by ethnicity, religion or wealth)

> same age

one of the thinks some of the nordic countries did change (through their suicide rates are high, but that is more a problem with the geographic location, i.e. not getting much (or any) sun-light in winter).

That is mostly a myth. While suicide rather in the Nordic countries are slightly above the European average they're not the highest in Europe and below the US. Also the correlation between suicide and not getting enough sun light is at best very weak. If you cluster suicide data on a pr county level in Sweden for example, you'll find a very high correlation with unemployment levels and negative population growth and no correlation with how far north you are.

Non of this does mean you are wrong, but also not that you are right. It's just way more complex and interlocked with other factors then just linear adding up some negative factors.
