Couple things here.
If you look at the birthrate prior to the sexual revolution and the birthrate after I have to ask you something.
Is this is more successful strategy than getting married young to a good husband and having a large family?
The problem is that it’s a terrible strategy. What if you don’t find ‘that good man who’s also single’? What then? You’re left a single mom - which is why we have so many of them. What happens to the children - they end up in poverty and that’s not a great outcome.
Whereas - if the woman waits, THEN gets married to a good man - stays married to the same man - what happens to her children after? They are more likely to see themselves better rather than worse off than their parents.
I am not convinced by the sexual revolution’s attempt to claim ‘evolution is in favor’. It makes sense that they would claim it - but I think the consequences are clear. More STDs, poorer relations and fewer children.
However you interpreted what I said, do not take it to mean that modern social mores are more in line with our evolved behavior.
The opposite is true. What is considered the traditional behavior of men and women is the healthier behavior for men, women, and society.
And it is healthier because it recognizes and seeks to manage the natural tendency of ungoverned passions to run amuck and destroy a society from within, as ours has been destroyed.
