The left criticizes the right for its alleged partisanship, extremism, intolerance and angst, when the left dwarfs the right in all these characteristics.
Contrary to leftist propaganda, mainstream conservatives haven't grown more strident or extreme -- unless you define extremists as those who are valiantly trying to preserve America's greatness and prevent the left from steamrolling its agenda against the will of the people.
At this point, conservatives would almost be happy just to preserve a modicum of the institutional greatness that has made this country the most extraordinary nation in world history.
Notwithstanding a recent Rasmussen poll revealing that Obama supporters believe tea party members constitute as great a threat to the country as Islamic terrorists, we don't see misbehavior, violence or extremism emanating from the maligned tea party. We do, however, see it from the leftist Occupy Wall Street movement and leftist union thugs.
It is the left that has grown dramatically more extreme and belligerent. The left has no interest in bipartisanship or camaraderie with the right except to the extent that it can secure support of useful, establishment Republicans to naively enable its extremist agenda.
Liberals are forcing their agenda on this nation bit by bit, dismantling its institutions brick by brick, but there is no satisfying them. With each victory, their appetite for more only increases. Likewise, with each defeat, they renew their resolve and redouble their efforts. They know they are rewarded for their relentlessness and their perseverance. They know that the right lacks the unity, the moral courage and the stamina to put as much on the line in behalf of its own ideas, so they think it's just a matter of time before they prevail.
The so-called wealthy pay dramatically more in income tax and most other taxes, both in terms of a percentage of their income and in actual dollars. The bottom half of income earners pay no income taxes; 20 percent of the people are on food stamps; and other welfare programs are bursting at the seams. But it's never enough for liberals, especially Obama. Until the wealthy are no longer wealthy, Obama will not be satisfied.
No matter what progress the nation has made on civil rights and race, it will not be enough for the left, for grievance is its lifeblood.
