Not at all. I'm a home school dad myself :-)
My children are 21 and 24. My son graduated from college two years ago; my daughter will graduate in May. Although I did not home-school, I taught them how to write. I made sure that they could create a well-written essay. Attending college here in Liberal Hell (a.k.a. Massachusetts), both of them were often at odds with their professors. My daughter had to write a paper extolling the virtues of single-payer health care. Needless to say, she took the opposite approach. The comments noted on her paper included “this is the best written essay I have read in years although I disagree with almost all your positions”. My son’s feminist English professor had similar comments when he was asked to write about something in his life that profoundly affected him. He wrote about his experiences becoming an Eagle Scout. (Her comments included that the Boy Scouts was a terrible organization and other such drivel. She thought he wrote well about a “bad influence”. But, that is a topic for another day.)
Although I did not exclusively home-school, I supplemented my children’s education. I guess one could call that “semi-home-schooling”.
