Yes, I was. From third grade to 12th.
I hated it.
It was in essence a mask for abuse and mediocre educating in the name of avoiding worldly indoctrination.
Would you homeschool your kids?
Possibly and under certain circumstances.
Homeschooling can only be properly done if both parents are 1) Agreeable to it, and 2) Are emotionally, spiritually and materially capable of it. If one parent balks, give up the idea. If I'm agreeable to it, but my wife isn't, then it won't work and shouldn't be done. If I'm not agreeable to it but a wife is, then it can't and shouldn't be done.
Public schools in many instances do seem to be a poor choice, but they're not the only choice. Plus, plenty of brilliant and even Godly people have made it out of public schools. Christ went to what was likely to be very liberal and ungodly synagogues and he turned out okay because his goal was God the father and His glory.
Personally, I would prefer to home school up until about 10 to 13 years of age. All the while being close to some kind of home school group that offers group teaching and activities. At a certain age, a public or private school should be looked into where they can become responsible for their more frequent interaction with others, become leaders, become examples and etc.
And any other thing y'all can think of for this thread please feel free to add it.
In my experience with fellow homeschoolers as I grew up, they were intellectuality intelligent and well spoken (I hate that phrase, "Well spoken", as a result of homeschooling). However, they (we) were very adept at manipulation, knowing how to behave to appeal to the adults. They (we) were bootlickers who attempted achievements to merely appeal to their own social circle. They (we) were arrogant about their station in life. In some cases, we appeared emotionally retarded... because some of us really were.
Manipulators? Man pleasers? Arrogant? Foolish? And we were supposed to be different from the world?
We just wore more "respectful" clothes and could use larger words. In essence we were the same as the public schooled kids. I believe the problem was that public school was the anti-goal. Any time you define yourself by a negative (we won't be like those ebil public schoolers!!), you tend to end up looking frighteningly like that thing. Just like you can't drive a car by focusing on the ditches to the left and right, you must focus on the positive and make the destination your goal. That can and has been successfully done via public schools, private schools and home education.
The argument that I often here use in favor of homeschool is that the public schools are so bad. It seems like a straw man argument to me. One thing being bad does not prove that another thing is good. One thing being bad doesn't automagically make another thing intrinsically better. "Guns have been used in violent crime! Let's get rid of guns!!" is attacking the symptom and not the problem.
Anyway, in spite of home schooling being so royally abused in my household, I'm not against it but it has given me a more responsible mindset towards it. It's not the panacea that many in the fundie camp seem to think it is.
