They never quit. They never will. It is much easier to tear down than to protect. They lose a battle and gear up for the next one. They plant weed seeds in the flower garden. Eventually the weeder dies or moves on.
That’s exactly it-it’s much easier to destroy than to create, as nations have repeatedly found to their cost. It’s one of the things that made the American Revolution so unique, and the nation of America so unique, which the left is working hard to destroy, destroying even the belief in our uniqueness. Every time some leftist revolution “succeeds”, it fails to replace whatever it destroyed with a functioning, prosperous, free government.
