Forgive them, Lord; they know not what they do.

The Left has always been destructive, of itself and the communities around it. Drugs, abortion, homosexuality, welfare state … if it takes the human being a notch closer to the animals, the Left is all for it.

One other thing the Left is good at, though, is an irritating talent for the most mind-bending rationalizations of its abberant behavior, rationalizations that have become institutionalized.

A prime example is the concept of racial profiling, which a court on Friday ruled Arizona Sheriff Joe Arpaio and deputies had committed by virtue of checking the citizenship of Latinos with whom they came in contact.

To the Left, this is a great sin and proof that Arpaio is a scoundrel. As the “objective” Associated Press put it, “The ruling marks a thorough repudiation of the immigration patrols that made Arpaio a national political figure, and it represents a victory for those who pushed the lawsuit.”

Go team.

Arpaio and his deputies, of course, are simply enforcing federal laws against illegal immigration, laws which the current Administration has essentially ignored. It also must be recalled that Arpaio tried to work with the feds on stopping the scourge of criminals coming over the border into Arizona, and he got sued for his trouble.

In other words, the Left set up a situation where Arpaio could only choose between ignoring the problem and letting criminals run roughshod over the people under his protection or doing the right thing.

Sheriff Joe chose to do the right thing.

Based on what is known about Arpaio, it is to be hoped that his response to the court will be the same as that to the feds, that he was elected to the job and he intends to fulfill his oath.

Other sheriffs are finding themselves at odds with the federal government as well. The Constitutional Sheriffs and Peace Officers Association is holding its convention this month, at which members will discuss ways they can protect their communities from federal overreach and defend citizens’ constitutional rights.

“We are going to train and vet them all, state by state, to understand and enforce the constitutionally protected rights of the people they serve, with an emphasis on state sovereignty and local autonomy,î said Executive Director Sheriff Richard Mack. “Then these local governments will issue our new Declaration to the Federal Government regarding the abuses that we will no longer tolerate or accept. Said declaration will be enforced by our Constitutional Sheriffs and Peace Officers. In short, the CSPOA will be the army to set our nation free.”

Note that last sentence.

From the beginning, the Obama Administration has been casting conservatives as the enemy of the state. By its persistence in this message, all the while circumventing the Constitution at every point, its arrogance has slowly created the enemy it has sought all along — a trained, armed force opposed to its agenda.

Some liberals have labeled the CSPOA “insurrectionists” and “traitors.” (Natural Tories, always running to defend the King.)

It’s just that sort of liberal arrogance that has pushed this country down the road to the point where not just a small clique of anti-federalists but the mass of gun owners and large numbers of sworn peace officers are ready to fight their own federal government.

A recent poll found almost a quarter of all Americans agree that violence may be needed in the near future to restore liberty. Even 18 percent of liberals in the survey agreed.

There is a group led by a guy named Adam Kokesh that is trying to organize an armed march on Washington, D.C., on July 4 in protest of federal efforts to restrict the Second Amendment. Many people have expressed concern over the true motives of the organizers, but the project seems to be moving forward. Plans are for gun owners to walk the streets leading to the Capitol, near the White House and other important locations while carrying their weapons.

Kokesh was recently arrested, but other organizers have vowed to move forward.

There are not enough fingers on your hands to count the ways this event could go wrong.

Whose oath of office is “more legal”? The president’s or the local sheriff’s? They’re both constitutionally sworn officers, both equally authorized and capable of determining what that oath means.

And yet, there’s a serious conflict brewing in this country, one that increasingly seems it may end up being settled by bloodshed.

Before that happens, and because such a fight might not go the way liberals hope, the Left might consider listening to what its fellow Americans are saying. Instead of telling conservatives to shut up, the Left should trying shutting its own mouth and opening its ears before we all live to regret it.
