To build a political system you must use the materials you have. If you were building a steel cable bridge you would not scream at the steel and tell it to change its material properties; similarly, you should not scream at humans and expect them to change their nature.
Work with the materials you have. Work with human nature. Never expect it to change.
Deluded liberals think they can change human nature.
Since a subset of humans are always deluded, getting liberals to change their nature is trying to change human nature.
Which is practicing liberalism.
Therefore; to argue with a liberal to try to change his nature is to become one. This is why the right perishes through dialectics.
Technology and capitalism are the exits.
