Akaemmafrost, thank you SO much for your post. Yes, the constant questioning, irrational judgments and foundationless beliefs that you are wrecking your children's lives would make anyone defensive. You also sound like you are doing a fabulous job with your ds.
Thank you too to those who said such nice things. I didn't want to disappear and not thank people for their kind words.
I had a little look around the Primary Education topics. From even a cursory read it is more than clear that there are often issues with the quality of schooling, with children of year 5 and year 6 being basically unable to read, with bullying and cliquey behaviours. I would say the proof of the pudding is in the eating, so to speak, and my dc are both reading absolutely fluently. When I took my dd out of school her handwriting was dreadful, her reading very patchy, and her maths atrocious. She had been ignored and neglected. It was not my child that did not have the ability to learn. That was proven when she started to read fluently within two weeks of being homeschooled. It was not that she was not able to write beautifully, because within a few weeks with me her handwriting improved beyond recognition. It was not that she was not able to spell, as within a month or so that too had improved dramatically. My daughter thrived at home, and wilted at school. I am not giving them my reading, writing, polite son, since he enjoys being homeschooled, and as long as he is thriving and happy, I know Im doing the right thing.
The only thing I will have to explain to her is why I persevered with the school system at all, why I did not homeschool earlier.
As for ruining their future...and go ahead flame me for boasting - my daughter, at this rate will be doing O'levels/GCSEs by the time she is 11 or so, and right now has been able to get a solid 65 percent in GCSE practice math papers. Her future is being secured by being homeschooled. She will have full access to formal qualifications and to university admission, since she is clearly academic, and even at this young age, it is her dream to be a scientist of some sort. I am ruining no one's life. However in the short, and possibly the long term, school was absolutely ruining her quality of life and mine too.
As for making friends. Well right now their friends are many and varied. They are not lonely in the slightest. They do not judge others by how they look, or if they have a medical condition, as my daughter was judged in school. They are polite, appropriate in their behaviour as you would expect for their abilities and ages, and most of all, fun.
As for irritating people out the house, I am going to stay polite and explain as many times as it is needed. Reading some of the replies reminded me how inflexible some people are, and how unable to process anything other than the absolute societal norm. I spend my time with so many open-minded, questioning, wonderful people, I do forget that not everyone is like that.
