I am a Gen Y-er. I have a 3-year-old and I plan to homeschool/unschool.
Whenever I discuss homeschooling with my peers, the #1 concern is socialization. Or, at least, that's what my peers say.
But I've been thinking: what my generation is really concerned about is that our homeschooled kids will be different from us. Because we are obsessed with being part of a group. We find our identity primarily from the group(s) we are a part of. We are not an individualistic generation (Point #2 http://blog.penelopetrunk.com/2011/07/15/what-gen-y-doesnt-know-about-itself/ )
We don't honestly believe we learned anything in school. We all hated school. But too many of us defend school; like you wrote, it's as if we have Stockholm syndrome (http://education.penelopetrunk.com/2014/03/17/3-reasons-your-kids-should-not-have-school-teachers/).
Too many of us Gen Y-ers don't have the guts to make a change for our children. We agree about all the tiny little things wrong with public schools. But too many of us want our kids to go through a 13-year hazing, anyway. Because the alternative of becoming a strong individual is unfathomable to us.
