A good answer.......

I just found another blogger's take on how to answer the why do you homeschool question.  I"ve included the parts that I most agree with (which is most of the post). 
A few excerpts from Why do you homeschool? – Homeschooling Five Part 1

I just found this post on one blogger's answer to why she homeschools.  Had to laugh out loud at this part of her answer to the oft assumed idea that you must have superhuman amounts of patience in order to homeschool your kids: " I am embarrassed to tell you that while teaching my son fractions one day I threw two halves of a potato at him after explaining to him for the eleventh time that a potato cut in half was not two potatoes, but I want to be honest with you."

"one of the main reasons we homeschool is because we believe that the model of compulsory education we now have in place stifles children from learning, being creative, and is waste of our time and theirs. Not only do we feel this way about public school education, but private school as well. I really don’t believe there are any great schools out there. What I believe is that there are better schools in different communities, often due to socio-economic class and parental involvement, but as long as schools are following current trends in education and No Child Left Behind, your child whether they are in a school with excellent standardized testing scores or poor ones, is getting at best a sub par education geared towards fake learning to pass a test at the end of the day.........I see the traditional model of school as glorified daycare. So much of what goes on between the time your child goes to school in the morning and the time they get home has absolutely nothing to do with educating our children. In fact schools are being used as a substitute for home and for things that should be taught at home. Some children are eating not one meal, but two meals a day at school. They are getting all their hygiene education, sex education, and drug education beginning in kindergarten, not to mention any political, social, and spiritual education from a teacher that you may or may not share the same values with. All of this “learning” should be conducted at home, by family, or by what I call “the village” that you surround yourself with. This is not the job of our government nor is it the job of the teachers to educate our children in this way.

Putting children in school in my eyes is training them to be a slave to the man, the machine that we now call our government, to not think for themselves and spit out what has been forced into their heads by a system that is failing in every way. Parents leave for work, drop their kids off and have little involvement in the actual education of their children. In fact, parents are unwelcome guests in most schools, requiring them to jump through hoops to observe teachers and the classroom environment that there children are in. Schools are the place where kids go so parents can work or have a break from parenting them instead of a place that fosters a love for learning and an environment that is conducive to creativity..........Our “book learning”, as I call it, is gotten in the same amount of time that the average child puts into homework each day. I spend less time “educating” my children per day than I did helping them with homework and projects when they were in school. I find it ridiculous to have kids in school seven hours per day than to send them home with busy work and projects that can take from anywhere to thirty minutes to several hours for them to complete. That is what should be going on at school. When they are at home, they should be playing and spending time their siblings, friends, and parents."
