Well as a feminist myself I have no truck with women who use their children as weapons.I have no truck with either sex doing that.
However there was a time when an abused wife leaving her children at the marital home because she did not have anywhere to take her children would lose custody of them and the abusive husband would most definitely use the children against the wife.
Things have changed enormously since the 50s and 60s thanks in part to feminists and to far sighted and empathetic men.
However I really think things have swung too far the other way and it is high time this fact was noted and things rebalanced.
