I think that to the majority of people, home schooling is "weird", mainly because they either didn't do it themselves/know anyone who has or they are just thankful they didn't have to do it themselves with their kids. Clearly it suits some people, but would not suit the majority. As far as i know, not having looked at any of the links, there's no compulsion to take exams and if you did want to go to further/higher education, you could get in on interview alone.
i know that's nothing to do with the OP, sorry pasta!
