Your eyes are brown.
He is exaggerating, but he is not that far from the truth. The left is dissatisfied with America and where it has been. They speak of "transformation" all the damn time. When you hear their ideas for this transformation, you realize they don't want America to be... well, America at all. They would much prefer a humble, socialist European state.
Given enough time and success at the transformation I'm sure there would be a movement to change the name of our country to something less offensive, more inclusive and representative of the indigenous peoples of North... uh... well insert the happiest naive word you can think of here. Or maybe just the United States of Namaste.
I'm only half joking. If you listen to the origins of most of the Left's ideas, meaning San Francisco, New York City, Chicago, etc and you close you're eyes and concentrate on this kind of thinking, this idea of "transforming" the country and even renaming it once the transformation is closer to completion, is much more clear.
The reason the right wing is so nasty and angry is people on the right like the country we are and have been. They like it a lot. They don't want "transformation" and ultimately, the Left is winning and the Right is losing. Frustration is bound to set in.
The big problem the Left doesn't fully comprehend is, if the Right is truly forced up on the ropes with threat of extinction too soon, the Right is well armed and it will be a blood bath. They will likely wait a generation or two until their control of the media and the education system is successful in indoctrinating 80%+ of the young people to the "correct" way of thinking, the courts they control have open the way to implement all their great new ideas and their laws, taxation and regulations wear the Right down to the point they are very weak.
Make no mistake, the Left intends to bury the Right. They are hopeful they can do it with "proper" education and not force.
