I work 60+ hours a week and if I can spend my free time improving the lives of kids I don't need social approval.
Not having kids isn't an argument, it's a logical fallacy people throw at you when they can't respond with a rational rebuttal.
It's the same bullshit people throw at you when you tell them that male privileged is bullshit or that the root of black poverty and crime isn't primarily racism.
They will say things like "you wouldn't know because you're not a woman", or "you wouldn't know because you're not not black". writing someone off because they aren't a parent is the same stupid bullshit.
In fact, if you didn't do research and really think about how you and your spouse would parent before becoming a parent, you should have never become one in the first place.
If there is EVER a time to be prepared with as much evidence and research as possible, it's for being a parent(the most important thing you could ever do in your life).
Also for the record, it's way more than 90%. the vast majority of parents NEVER think about their parenting styles, they just react to their kids in the moment and fall back to doing what their parents did with them.
Who gives a shit what people agree with. I certainly don't give a shit unless they have evidence. This goes for work and science and especially for parenting.
