There is research to back it up. I posted it somewhere else, but when I set up the WATCH D.O.G.S. program at my kids' school, I had a whole slide about the consequences of fatherlessness, or not having a father figure. It's a thing. Not sure it's necessarily a thing for this thread, since I'm not aware that we have any idea what the home life is for the kids involved in the B Rob shooting...
Anyway, you can learn more at
https://fathers.com/ if you so choose.
It's actually a great website for Dads.
