For every one of your wife there's another who did just fine. Given that the majority of universities up until just recently were religious, I find it difficult to understand your conflation of religion with ignorance. Are there extremists? Of course... but overall, the idea that just because something is religious it's less educational is... bad. I mean, before public schools in America (and still in Canada), Catholic parochial schooling was the largest school system, and still is the largest private one.
A religious school system is still required to adhere to a modicum of technical standards for the various studies, and what makes home schooling both worse and dangerous is how incredibly unregulated it is. See the above itinerary as described in the LWT piece: nothing but bible readings and chores. This is not how you raise capable people, this is how you raise house servants.
