That is very unkind and indefensible. Many good and concerned parents have children who are not successful or not good people. You can lead a horse to water but you can’t make them drink. While good,involved parenting improves the chance that the children will become virtuous adults, it does not ensure that result, nor does neglect ensure a selfcentered criminal.
You make some excellent points.
It would be interesting to survey members of Free Republic, and see :
How many of us have children who are more liberal than we are
How many have fallen away from the faith they were raised in?
How many got involved with people who are more liberal?
How many send their children to public school?
Your observations are very wise. We all have free will.
