As a father I can assure you you have no idea what you're talking about.
And what's society without kids? Whether you're a parent or not, we need kids to do well. It makes no sense at all not to learn to be good with kids, to care about them, to invest in them, etc. They're firmly a core component of human society, certainly not going anywhere.
And I can't imagine not spending a lot of time with my kids. It's one of the things I think about most. I like to do a lot of things, but they're one of the few things I can always say yes to. I want to take care of them, teach them, learn from them, listen to them, see them grow, whatever. It just feels good to be in their lives. There's nothing unnatural about it.
I don't have kids and it still sounds nonsensical. As a man, my instinct isn't to run away from my child if I had one. If life keeps men and their children apart, that's a different matter altogether. But I have seen other men yearn to be with their little kids. My father did the same when I was young. Some of them are their kids' sole caregiver for the majority of the time because life keeps the mother away from the child. And in all instances, I see strong paternal affection and instincts at play. I'm baffled by an assertion otherwise.
Note also that a lot of what we consider "fatherhood" is a Western construct of the last 150 years, with falling birth rates and diffused wealth. Things were very different when families were poor and sprawling: fathers simply did not have significant time to spend with all their kids, when they had a dozen of them and were out of the house most of the day for work. Significant bonds would be developed only while working together, later in life.
That said, a lot of people don't bond for the sake of bonding, but bond over a shared task (one that really needs doing, not an invented game that mimicks a task..)
The bond I have with my children is profound and primal. The idea that it’s “unnatural” for me to spend much time with them is so ridiculous as to be instantly dismissed.
GP clearly doesn’t have kids or have close male friends who are involved with their kids.
for every helicopter dad there are ten guys who don't care about their offspring.
