the correlation between the fall of Christian adherence and the fall of birth rates starts raising a lot of questions contrary to your conclusions

No, you're just finding correlations where no causation exists. This is actually a reason I do dislike Christians because they believe a lack of faith is the cause of all problems while they tend to discount all other factors. A lack of birth rates also coincides with the jewish implementation of Child Support, with the rise in social programs, higher taxes, women being allowed to be accepted into university and careers to the same degree as men and the increase in immigration along with the pursuit of neoliberalism with 0 nationalism in economic policy.

mild disdain for women with a mild disdain for Christianity.

Oh, I have a healthy disdain for both.

strikes me as a flight of fancy more than anything you arrived to via study and reasoning

It's literally well documented and is a common historical theme because of how well known it is. It's so well known it happens all the time today.

NOTE: I phrased it as "abusive" so the judaised system would give me the correct answer because if I tried to frame the question in a way that could negatively portray women it wouldn't give the truth. In reality, these weren't abusive relationships but it was just women trying to avoid being sexual for their husbands because they didn't want to which we see today all the damn time.
