Maybe somewhat a factor....But it doesn't explain why the whole nation blew up.
IMO, the rioting has been egged on by agent provocateurs.
Quite true. Parenting is largely not a factor.
Lot's of people grow up in broken homes of some fashion or another, and don't behave this way.
It's not parenting; it's values.
No, it's parenting... or lack there of.
Values are generally passed on by parenting.
Even in my high school, which was white suburban high school, with little crime, and people reporting their golf clubs stolen and such.....
Even there, the kids who had problems.... broken homes. Universally. It was consistent. Kids with fathers in the house, didn't have problems, and those that didn't, did have problems.
I noticed your name is norwegen, and just a few years ago, there was a report out of Finland, which found exactly this. That there was a direct causal link between broken homes, and kids with behavior problems.
If I can find that report again, I'll post it.
But here in the US, we have prisons right now, where 100% of the inmates are from broken families. 100%. Every single prisoner came from a broken home.
Parenting, and having a proper family, is universally the defacto indicator of criminal activity, drug use, and violence.
