Interestingly, it was Northern Premillenialism that turned into Progressivism. Southern Premillenialism focused more on individual salvation.
"In the Ethics of Liberty, Rothbard explores in terms of self-ownership and contract several contentious issues regarding children's rights. These include women's right to abortion, proscriptions on parents aggressing against children once they are born, and the issue of the state forcing parents to care for children, including those with severe health problems. He also holds children have the right to "run away" from parents and seek new guardians as soon as they are able to choose to do so. He suggested parents have the right to put a child out for adoption or even sell the rights to the child in a voluntary contract, which he feels is more humane than artificial governmental restriction of the number of children available to willing and often superior parents."
"He also discusses how the current juvenile justice system punishes children for making "adult" choices, such as underage drinking or sex, removing children unnecessarily and against their will from parents, often putting them in uncaring and even brutal foster care or juvenile facilities, while at the same time denying to them those legal rights adults enjoy, such as trial by jury, a written transcript of their court proceedings, etc."
You haven't spoiled any party. The Word of the living God stands for all eternity while the discredited-in-matters-of-Scripture Murray N. Rothbard is, well, dead, along with, it would seem, some of his ideas.
I read much of the first link. Murry calls them postmills not premills.
The posters think man is good enough to force them to be even better and thus create a kingdom good enough to hand over to Jesus.
