(admitted sexist remark alert)
It's because that makes them one generation removed from a man and woman in a family sharing responsibilities and guidance of children. The feminist refusal to take her husband's name symbolizes her decision to thwart, dominate and belittle him. The confusion, lack of direction and lack of a strong positive male role model leaves the offspring to look for a gang as a substitute or antisocial behavior to release anger.
Lack of God and Bible in the home are frequently found with the above stereotype I made above in my sexist remarks.
