To understand the schism between the basic ideologies of Liberal vrs. Conservative, it would be good for those interested to read George Lakoff's books, "Don't Think of an Elephant" and "Moral Politics". This would explain the conversion of the Dixiecrat parties
to the Republican.

Essentially, Republicanism is based on an authoritarian view of people. The Liberal point of view is essentially that of a nurturing or compassionate view of people. The concepts have been at loggerheads for a long time. The authoritarian worldview finds roots in orthodox religions and a military mindset. The Liberal point of view tends toward helping, aiding and protecting the rights of the innocent.

A person can hold both views at the same time whereby they profess ideas one way and act another. Lakoff calls them "biconceptuals".

Unfortunately there are many Dems who think like Repubs today. This is due to religious indoctrination, strict parental upbringing and other factors. This is why the US is embroiled in meaningless "wars" that have no solution or end. Punishing is a big part of the authoritarian viewpoint. Bagram. Guantanamo.

The Repubs don't get it that you can't torture information out of a committed ideologue.
They like punishment.

A punitive approach to governing is disastrous. It leads to tyranny and dictatorships.
