marfisa I totally disagree with many of your points.
Your experience of HE is with a mother who was not psychologically able to HE. That means that she probably shouldn't have done so. Mothers/Fathers who are not in that position would therefore not cause the problems that you experienced.
"- for better or for worse, it's always more about the parents than the kids."
You have absolutely no evidence for this whatsoever. It rather comes down to the "mothers who breastfeed beyond 6 weeks/6 months/ a year/ [insert your random bias here] do it only for themselves" whereas actually those parents who are in that situation are the ones who know what they're giving to their chldren, and giving up in their own lives.
"- there should be regular comprehensive checks on HE families to make sure everything isn't going pear-shaped. HE families who are doing it right shouldn't mind this because vulnerable children have to be protected. They're not their parents' property. I feel quite strongly about this. Often the first sign of gross parental neglect emerges when kids stop going to school. When kids are HE'ed in the first place, people outside the home don't get that key notification that things may be badly amiss."
This statement strongly implies that HE families are neglectful or abusive which is another appalling myth. Of course some abusive families may have children who are kept out of school, BUT, MANY abusive families send their children to school and the school totally fails to pick up on it. There is NO link between HE and abuse and to say that there is is offensive as well as being factually incorrect.
"And while my parents may have had psychological issues, and did not know anything about early childhood education specifically, at least they were effing LITERATE. Don't even get me started on the myriad HE parents, especially in the US, who can't write or spell but somehow think they are qualified to HE!? Those poor kids."
I don't understand this "point". Certainly a parent who isn't educated (or able to self educate) enough to facilite the education of a child isn't a great candidate to be a HE parent. But I hardly think that this applies to the OP, or to HE parents in general. Furthermore I've received 14 CVs today for a position that I have available. All the candidates went to school. Not ONE candidate has more than 2 GCSEs over grade C and EVERY ONE has serious spelling or grammar errors. I hardly think that this shows how brilliant school is.
"On the other hand, going to school certainly increases the chances that a child will be able to forge a variety of strong relationships with other children and adults. There is simply more opportunity. "
Not right at all. At school children are generally kept in their own age groups, whereas HE children are often given the opportunity to meet in HE groups where there are a wide range of ages that they have to learn to socialise with. Frequently HE children meet these groups regularly (sometimes several times a week) so they have ongoing opportunities to form deep relationships and to practise social skills.
You clearly had a tough time and I very much sympathise, but you are really making some awful and unfair generalisations, as well as perpetuating some of the offensive and wrong myths about HE.
