That has always been the case. Children have been indoctrinated.
Perhaps I have had an irregular experience, but I was born in the 70s and grew up in the 80s and 90s and the whole of my primary, secondary and further education has been at Anglican institutions. This in addition to Scouting and church youth clubs, but I have never felt that there was any compulsion on me to believe or observe regularly, nor have I encountered any condescension towards other faiths or denominations; in fact, there was a great deal of 'this is what the church teaches, now you must decide what you think--it's no use my telling you what to believe'. The whole thing was reinforced through my studies: it's scarcely possible to understand the English canon or British history without picking up swathes of Christian debate and theological/ecclesiastical language along the way, but the last time I checked in with the education world, they weren't even requiring teenagers to read whole novels at school. I fear that much will be lost.
My parents' generation of our family are pretty much irreligious, but my brother and me were sent to these specific institutions as they were the best in terms of educational outcomes. The result--and this is what I had in mind when I wrote that the majority today lack the philosophical and theological framework to make use of faith--is that I
understand where it's all coming from, even when I can't credit specific claims; I understand (at a basic level, I'm no theologist) the questions for which they are seeking answers and why they think them worth seeking. If this was indoctrination, I can scarcely think of a milder or more benign form.
As a child I said my prayers at bedtime because my grandfather taught me to; as an adult, I sometimes do the same because I see the value of meditating on the day passed as well as that to come. I can't know whether there is truly any being to note the entreaties of petitionary prayer, but to put one's day on hold, step into silence and hope earnestly for another's suffering to be ameliorated seems to me to nurture empathy and deepen one's moral sensibilities.
As an ongoing project, I'm a still a pretty shoddy specimen, but I feel as if I have been given the tools to one day produce something tolerable from the materials I have. The way I see it, an increasing number in the west have no conception of what such a project would even consist of, let alone what value could be gleaned from embarking on one.
Apologies if this is a bit of a ramble.
