I decided to homeschool D as a direct response to the chaos and time-sickness that seemed to be everywhere we turned:

"Rescuing the next generation from the cult of speed means reinventing our whole philosophy of childhood, much as the Romantics did two centuries ago. More freedom and fluidity in education, more emphasis on learning as a pleasure, more room for unstructured play, less obsession with making every second count, less pressure to mimic adult mores." From In Praise of Slowness

This best sums up the reasons I chose to homeschool... and of course there is also a list of specific reasons that I could add as well.
