Want to have some low cost fun with nary a hangover afterward? Get some homeschoolers in a room with some public schoolers and some attachment parents with some bottlefeeders and then yell out "Hey. What's with you people?!"
If you include a mud pit and a video, you could make some bank.
Seriously, though, homeschoolers often get a bad rap (weird right-wing Christian types whose children lack social skills), and seem stumped as to why non-homeschoolers seem so exercised rude about their choice. The Eclectic Homeschooler describes an exchange with a curious onlooker and wonders at the questioner's obvious belief that homeschooled children lack social skills as well as access to sports opportunities.
The bias against homeschool isn't simply that people are critical of what they don't understand. It also relates to a fundamental belief that children should be educated in a classroom, along with their peers, though clearly the days of the peaceful one-room schoolhouse, or effective public school are more or less long gone. On another level, many parents are critical and/or defensive about homeschooling because they feel threatened by someone else's apparently superior committment to their children.
In a day and age when "Are you a good parent?" is the subtext of nearly all dialog about childraising, it's no wonder that everyone's choices are under fire (and investigation).
