The term used for a state of mind in which liberals and most democrats seem unable to come to the realization that the world is not perfect and will never be perfect. Using propaganda such as "world peace" and "end world hunger" attract many people, supporting the concept that democrats/liberals/hippies win misinformed people over with compassion instead of common sense. The world is practically collapsing, socially and economically, and the democrats/liberals/hippies seem to be unaware or ignore it. The liberal utopia will always exist in their heads, but never in reality, thus they are in La La Land.
Student 1: "Holy fuck, I am sick and tired of these kids who think they know everything when really they just state opinions instead of facts and events."
Student 3: "Dude, there is nothing we can do to fix their minds, they've reached a point of no return as you can see from the Obama t-shirt. There in La La Land."
