Never said it was. No male vs female issue here. It is world vs God. You seem to be focused on the world. Look you are basically proving my point anyways. You seem uncomfortable with what I am saying, so then you lash out at me personally. Let me rephrase the question you didn't answer.
Please explain to me how knowing the above, changes how one lives their current Catholic life? How would one prepare differently because they know?

I'll spell it out for you:
- A lack of marriages are
partially due to women being overly-picky.
- A lack of marriages is a societal problem, with very bad consequences, for the Church and society.
- Age-gaps are an example of being overly-picky.
- Realizing that age-gap pickiness is a problem, helps to counter the false-narrative, which helps the Church.
Admitting there is a problem, is the first step to fixing it. As a woman, if you don't admit this is a problem, then you will be unable to help other women see the problem.
This problem is bigger than you. It's about helping society, not just your own, personal catholic life.
