"Homeschooling" means "learning at home". Not being locked inside a house for
24 hours a day. And, every sane parent wants their children to socialize with
other children (also homeschooled or not) and do whatever they want, on their
free time.
There are thousands of persons who were successfully educated this way (and
that's even how many people were educated before the actual system was
enforced, by the way - and every honest comparison of results usually puts
people - even 200 years ago, in the US, for example - who were homeschooled
in a better position as those who are educated, nowadays, through the
Prussian model -

And this same persons don't have social problems of any kind. (From what I
know, even, the most problematic children are the ones who are forced to go
into public schools...)
Not being a part of (or going along with) the "herd" is, most of the times,
actually a good thing. And homeschooling is also a great way to develop
independent thought and independence of action (that comes out of having to
rely more on yourself) - which can lead to great results. (Take a look at
Richard Stallman and Linus Torvalds, for example. Did they develop their own
ideas as part of a school project? Or did they do it because they started to
evolve on their own and following their own path?)
I know that intelligence is mainly one thing a person is born with. But, the
same way a better piece of software can make the same piece of hardware
function better, also the environment and the stimulation a child is
subjected to, when it's growing, is very important in how that same
intelligence is developed, is better worked upon and manifests itself.
Anyway, in your country, this a discussion people are not even allowed to
have. Since that, German children belong to the State and not to their own
families. And people who want to educate their own children are forced to
leave the country.
