Well there's you. You want religion to disappear.
I'd be very happy if it did (though not equally - vastly more so with some than with others), but unsurprisingly you're already squirming. Let's not forget that you said:
The Stalinists are those wanting the eradication by any means of religion
you have said that you don't mind if that is through mere apathy so you are prepared for the eradication of religion by any means
Gradual attrition through apathy is not eradication because eradication implies and entails deliberate, conscious and purposive removal, though it's no surprise to me that it's another item in your lexicon of words that you don't understand.
....even by the means of ''cohort replacement''....which sounds good but I can forsee it going the way of other faddish antitheist bullshit hypotheses.
In other words you are turning a sociological theory into a desire........and THAT my dear friend....is Stalinism.
Cohort replacement (which is a observable sociological phenomenon, by the way, not a hypothesis) is descriptive, not prescriptive - it describes what actually happens, not whether it should or shouldn't.
The fact that in terms of the waning of religious belief I find it highly desirable is entirely separate
