What the liberals want is to destroy the existing American culture. They want to destroy our power militarily, economically, and morally.
They want our military to be subservient to other nations via the UN. They want our economy to be subservient to other nations via ridiculous treaties such as those that redistribute wealth from the U.S. to 3rd world kleptocracies (e.g. the fines in the Kyoto Global Warming nonsense). They want to legalize gay marriage and abortion on demand in order to further destroy our nuclear family concept.
They want to destroy our concept of art, too. They want to claim that welding together rusted pieces of scrap iron is somehow "beautiful." They want such trash displayed in as many public places as possible, and in the meantime they want all forms of patriotic, religious, and/or truly beautiful art to be banned from public display.
They want to destroy our concept of *who* looks good, engaging in attempts to pass off starving waifs as sex symbols, and they want to destroy our confidence in what we eat...capriciously claiming that one food after another is "bad" for us, etc.
They want our nightly news to focus on the "bad" in the world, commercializing the politics of personal destruction as well as broadcasting every tragedy that makes the daily police blotters...all in an attempt to somehow sour Americans on our own culture and communities.
Thus, our enemies both foreign and domestic want to hamstring America with treaties and regulations that are painful for us to abide by...our "art" is tarnished with public displays of literal trash...our food supply and eating habits are constantly "questioned"...and the drumbeat of our local news is always to the sound of an imminent trainwreck.
