I found this at townhall and sums up where we are now.
The left subscribes to the French Revolution, whose guiding principles were "Liberty, Equality, Fraternity." The right subscribes to the American formula, "Life, Liberty and the Pursuit of Happiness." The French/European notion of equality is not mentioned. The right rejects the French Revolution and does not hold Western Europe as a model. The left does. That alone makes right and left irreconcilable
