So help my feeble female mind then. If you don't know if they used NFP, abstinence, something in the water, or birth control, then how do you come to the conclusion/fact that they "cheated"?
Without placing blame on anyone in particular,
There seems to be a genuine epidemic of small families among Baby Boomers (both Trad non-Trad -- the Baby Boomer culture/values/choices seem to extend into all religions)
What would you call it? Broadly speaking, as a group most of them "got out of" the normal struggles that life normally throws at a young married couple on this earth. Having a small family of 3 or 4 children in public school is a WHOLE DIFFERENT ANIMAL than having a larger family and homeschooling them.
If they had become Trad/informed Catholics sooner, they would have had a chance to make permanent changes. But when you happen to convert after childbearing age, then it's "too late". Not saying they waited on purpose to convert either -- that's just how it happened for the majority of that generation.
Having a large family just doesn't seem to be part of Baby Boomer values.
Their values included insuring everything, college education for each child, and wanting their children to "have it better than they did" -- but that "better" was to be measured in strictly material terms. They also placed a high value on "doing what everybody else does" and in general they invented the concept of the American Dream. They place an over-emphasis on homeownership. My mother (for example) thinks that apartments are for druggies, alcoholics, and those who have declared bankruptcy one or more times in their low, low lives.
Anyhow, those that converted to (or discovered) Traditional Catholicism can move on with their lives, and even save their souls.
But there are permanent consequences, for all parties. These permanent consequences and realities are worth drawing attention to and discussing. It will result in better understanding.
We are left with the aftermath -- the massive social reality
that we all are affected by, that countless 50-65 year old Catholics just don't understand and can't relate to their children as far as living a normal (Traditional) Catholic lifestyle.
How many Catholics of child-bearing age today have Baby Boomer parents that just don't understand? Parents that can't give any advice about what we're going through? How many of these children of Baby Boomers have followed in their parents' footsteps out of trust or filial devotion, only to be burned by it (for example, the value that "college education = success")?
