??? You serious clark?And mostly from the paternal side.
What percentage of men do you think abandon their family versus get kicked out of the family by the mom and the courts?
Mostly bad parenting is locked in by behavior prior to the pregnancy. You have an irresponsible male and female that 17 around and unfortunately it's the kid that finds out. I'd suspect most of the bad parenting is pretty evenly split, except society doesn't tell fathers that it's normal and ok for men to abandon their families and children. But women are not treated like the monsters they are acting like when they blow up the family and fight to have their father on an every other weekend schedule because they're "unhappy."
