We first heard of homeschooling on a 1985 or 1986 Focus on the Family program in which Dr. Dobson interviewed
Dr. Raymond Moore. We attended a day-long video seminar hosted by Dr. Moore's daughter and another by
Gregg Harris, both in 1986. The long and short of it is that we homeschooled our munchkins "K-12".
Homeschooling is not an easy thing. While not burdened with time overhead stuff built into PSs' one-size fits-all mass instruction, homeschooling pretty much means a family will be single income, plus or minus something part-time supplemental. Homeschooling also means one-on-one instruction; kids can't be plopped in front of the TV or computer to watch videos all day. OTOH, teaching your child, day by day, how to read and watching the "light bulb" go on and get brighter every day is a really cool experience!
The, "What about socialization?" meme is a straw-man red herring. It assumes, unrealistically, that PS "socialization" is universally positive. Ummmmm ....... no. It assumes, unrealistically, that homeschooling parents keep their kids indoors 24x7x52. In the real world, homeschooled kids go to church, participate in sports through Little League and other community sports leagues, and participate in groups like Boy Scouts, Girl Scouts, and Trail Life.
Within the homeschooling community there are support groups that have weekly park days and regular field trips (homeschooled kids have to be taught how to stand in line somehow!), sports leagues, and choirs. Granted, we live in Silicon Valley (population 1.5-2 million) but we had to pick and choose our kids' out of the house activities.
The only homeschooling parent I ever "met" (online discussion forum) whose kids were isolated was a woman who
did not want her kids around "Fundamentalist" (she used the term as a broad-broom epithet, not to identify, accurately, a particular variety of Christian) Christians or school-at-home (duplicating a school classroom in the home, with equipment, textbooks, etc.) homeschoolers. IOW, despite living in Orange County, California, near millions of people,
her rather bigoted choices isolated her children.
