No saying you are exactly doing that, but it was a warning in anticipation that the discourse might lead there.
But at the same time, this quote seem to imply that this is not his problem if he can't have children, but throws the blame on the woman rather than him taking responsiblity about his situation and do something to change it.
That's the thing. Are you looking for someone to marry and have children with? Or are you waiting for them to appear out of thin air... Are you putting in the work?
If you don't have success with dating, chances are you need to work on yourself. This applies to women as well.
A lot of women can't find a relationship or stay in fulfilling ones because they don't work on themselves.
The thing is, for a very long time, it was quite easy for men to find a relationship. I remember being young and being told that I should "give this guy a chance". I'm not the only one who was educated this way.
Now women don't want to experience certain things anymore in dating & relationships, and I am not talking about them wanting to live in mansions with men that have 10 inch dicks and look like romance novel covers.
So some men act surprised that they have to work on themselves in order to meet somebody. Because in the past the bar was really low for men. And in some eras, men could just be given a wife and that woman had no choice but to marry him.
From my childhood days I've always been told I needed to keep my weight down, dress a certain way, have impeccable hygiene, maximize my beauty, act modest, be forgiving, do this, do that in order to attract boyfriends or even just platonic friendships. Now it's all about healing your trauma, self help, fitness, emotional management, maximizing youth, cultivating humor and charm, being stylish etc.
Some of this stuff is arbitrary and oppressive but some of it is actually really important, and it's all work. It turns out that to have fulfilling human connections you have to work on yourself.
