1. Im not a father.  So, your assumptions about me are both wrong, and stupid.
2. Kids have been growing up without a full set of parents forever - and have turned out just fine.  "More likely" equates to what exactly?  What percentage of kids who dont grow up with a father/mother turn out bad?  What about the kids who have both a mom and a dad throughout their entire childhood and end up murdering mass amounts of people?
3.  Its misogynistic to only think Dads are the key to a kids success, or to use that as a reasoning behind what Dylan Roof did, as opposed to, you know, accepting the fact that hes an insane person.

Also - what about moms?  Seems all your research is just about how important Dads are.  Interisting.
