I don't use the term "liberal" much, since it's lost its real meaning. Now it just means socialist.
Leftist or socialist principles:
Capitialism is an evil system
The American dream is a lie
The system is rigged for the haves and against the have nots
The United States is a source of evil in the World
The Constitution and therefore the United States was created to benefit the wealthy and to exploit the poor and the working class
Government, especially the elite enlightened, are there to create a system that saves men from themselves
Private property is theft
These are just a few of the principles. I can go on if you'd like
That's good. Hope you don't mind but I am copying them.
