I'm not talking about you Vlad, I'm talking about the general population when and where you were growing up.
You claimed that most people were secular humanists - I challenged you on that given that even growing up through the 1960s and 70s (later than you) the concepts of secularism and humanism were pretty well invisible - how on earth do you know that most people were secular humanists Vlad - I think you are talking junk. I would suggest the reality was that most people were either church going christians or non church goers who still considered themselves to basically be christian and certainly not secular humanists.
Certainly I don't think that the concepts of secularism nor humanism were ever discussed during my (non faith) schooling, the default was always christianity.
secular humanists are still in confusion over what they are today.
I know the default was ''anglican'' but that was merely for forms,etc
indeed the BHA has taken the lead in reversing what it sees as a historical and habitual propensity to tick the Anglican box on the census.
CS Lewises books written in the 40's were aimed at a whole population for whom being Christian was merely trying to live a good life and doing good deeds....basically a form of secular humanism.
