I guess I didn't fully get the point in my mind across. Yeah, some people are poor caregivers (like most anything in life), but some people also don't expend the energy to be competent caregivers (that is, they are perfectly capable of getting kids their dressed in the morning, but for whatever reason, can't get their brains around it). Of course, in the States at least, the cultural tradition, set over generations, is that fathers are to provide for their families, and mothers do the dirty work of raising children. So, for many fathers, their task ends when they get home from work--"there, I've put the proverbial food on the table, now leave me alone so I can rest."
My grandfather used to beat the crap out of my dad with his belt. My dad decided he didn't want to do that to me. I'm deciding to be a more involved dad than father have by historical standards. I don't think I'm alone.
The linked article is saying there are a lot of other dads out there like me but the rest of society hasn't caught up yet.
I agree completely. My hope, too, is that more dad's like us (I was the "primary caregiver" for large swaths of time when my wife was in grad school) will change the perception.
