(I absolutely agree that no one's clocking all the circumstances here. It's true: we react with more shock and horror to people failing their own children than we do to other people actively victimizing those same children, because we have a moral knee-jerk that the failing is somehow "worse.")
The point is that we are unsurprised and lacking in outrage about certain crimes because we "expect" them -- and sometimes this means we'll give harsher punishment for crimes we somehow don't "expect." Even if the crimes are similar, or our expectations are wrong.
In any case: the reason I was asking after your thrust here is that I think it's dangerous to morally equate not being around your child (a problematic thing that's nonetheless done by loads of people without anyone dying) with actual involvement or complicity in torture, abuse, and manslaughter. I find it really hard to believe that you think that, or that you'd apply that same standard in other cases.
His family was at the child's wake, but I can't recall anything about him specifically. I'd be a little wary about making claims of "abandonment" without knowing anything about it; for all we know, he's deceased.
(It comes from the other direction, too -- there's a form of low-expectations bigotry involved in being somehow "unsurprised" that a man would beat a child to death (we put that down to a tragedy we almost "expect" to happen, to someone, somewhere), but being extraordinarily shocked and appalled that the child's mother would be either complicit in it or hapless to stop it.)
Which is part of why I think any defense of abortion rights over the long term actually needs to provide space for people with objections to it to voice those objections and feel like they're being taken seriously -- because when there's no outlet for that sentiment, and when it can't be contained someplace where people can peacefully dissent, it radicalizes further and moves toward violence.
I know you're not equating poverty with laziness -- it was just an example of something that sometimes requires race to understand. You can look at a lot of urban poverty and say, well, there is a whole history here, a big long story that has to do with race, and that's critical to understanding what's going on. But if you try too hard to keep race out of everything, you might just look at the disproportionate number of black people involved and say "well, it must be something about them that explains this."
(This is a weird conversation to be having on this site, a place that spends a lot of time paying good attention to the hard-to-escape ways the constructs of sex and gender work in the world!)
I mean, similarly, we could say that men and women are all people, and gendered distinctions are meaningless and "confusing." But then we'd be abandoning the true thing about the universe that explains why women have very different lives and opportunities than men -- not because they've made it that way themselves, but because there are things called sex and gender that have meaningful effects on people's lives!
