Yes. Absolutely.
Not remotely close. Forget about traits for a minute, you’re talking about two people doing a task vs one person.
This is probably less than ideal, but better than a single parent.
Brick’s covered a lot of this already. My stepson’s mother was always more attuned to his moment-to-moment feelings of emotional and physical well-being. I was always more attuned to his long-term development into a man. For some examples…
She would discourage things like risky play, whereas I’d let him horse around without much concern for things like scrapes and bruises.
I would be perfectly happy to stand my ground and physically keep him in his room if I told him he was grounded, she would typically cave on her attempts at imposing consequences.
I always considered an upset child to be the desired outcome of correcting bad behavior, but upsetting her child upset her too. She was and is a loving and caring mother but she, like many women, lack the same capacity most men have to do things that upset their children so they can grow into better adults.
By the time boys start growing into man-sized and man-strength bodies, the situation can change even more. Teenage boys are much, much better off if they know they can’t push dad around, whether it’s physically, mentally or emotionally. Teenagers need frequent behavioral checks, and you can’t check the behavior if you aren’t strong enough. A single mom can be a pillar of strength in her own way, but if her son has 100 lbs on her and his own ideas of what he can and can’t do, there isn’t a thing mom can do to stop her son in that moment.
There is, but it only spans all of recorded history, so you should probably hear those modern feminists out.
You can look around you and observe what you see, for starters. If you stop by your local brick factory you will probably notice the lack of women stacking hot bricks off of the production line. Has your plumbing ever been installed or fixed by a woman?
Would you drop off your toddler at a daycare staffed exclusively by men, even if you could find one like that? If you were gravely injured and required care and attention, would you rather have a beautiful female nurse take care of you or a bearded, muscle-bound, heavily-tattooed hulk of a male nurse who hangs out with bikers on the weekend?
For something more academic, there are now decades of data linking all kinds of bad outcomes to single parent households and lack of fatherhood. Exceptions exist and lots of single moms raise children who grow up into great adults. It’s just that so many do not. The child of a single mother is dramatically more likely to be a deeply troubled adult and not contribute positively to society.
