One of the classic objections to homeschooling is "But what about socialization?" The questioner wants to know how your kid is going to get out in the world and learn to deal with non-family people. We just got back from the Community Performance Series's production of The Sound of Music. Of course, it's a musical with lots of young people.
Of the 18 children (18 & younger), 5 are home-schooled and 13 are government schooled. According to the National Center for Education Statistics, the percentage of children being homeschooled was 2.2% in 2003. That figure is probably higher now; maybe as much as 3%. 3% of 18 children is, um, a half a child. If homeschooled kids were not well socialized, they wouldn't be given a chance to perform in a musical like the SoM. They probably wouldn't even be interested in it.
