Ive dated two girls who were home schooled. One was very nice but very shy (that could just be her personality though) the other was very bible toting and quoting scriptures like Rain Man... ask her about algebra or physics and she'd say it's not of any use in the real world.
BOTH were very touchy on the fact that they were home schooled. Only had to ask about it and they'd bite your head off and defend home schooling to the hilt and try to prove to you that they're not stupid.
I dont think home schooling in itself is bad. JRR Tolkein was homeschooled and he was a very very clever man. But it's not in every stay at home JW mother to teach her kids. Or dad.
