After the neo-Nazi demonstration in Charlottesville, Va., William F. Buckley Jr. must have been rolling over in his grave. As the founder of the National Review magazine, Buckley was an important catalyst for the modern conservative movement. Perhaps his greatest service was marginalizing extremists to prevent them from gaining ascendancy within Republican ranks.

In his bid to make conservative politics mainstream, which over time allowed for someone like Ronald Reagan to become governor of California and later president of the United States, Buckley singled out the John Birch Society and Ayn Rand as unacceptable. Why he went after the Birchers and the author of Atlas Shrugged may offer a lesson for todays GOP.

First and foremost, Buckley sought a politics based on rationalism, facts, empiricism and expertise. At the cost of rationalism, the Birchers were prone to embracing oddball conspiracy theories.

In one outlandish charge, Bircher leader Robert Welch charged that President Dwight D. Eisenhower was a communist agent. He further asserted that 50 percent to 70 percent of the U.S. government was communist-controlled.

Incidentally, it was during a 1964 meeting in Palm Beach that a plan was hatched between Buckley and then.-Sen. Barry Goldwater to denounce Welch. In a subsequent article, Buckley warned about the head Bircher being a liability for conservatives since he was far removed from common sense.

What Buckley did was use alternative media (which the National Review was) to neutralize fake news and keep it from corrupting the overall conservative movement. Today, unfortunately, the opposite has been occurring along with a president aiding and abetting disinformation.

Second, Buckley was a serious Catholic with sincere faith. Consequently, he was a staunch champion of the Judeo-Christian tradition. This is why he had no patience for Rand, who reduced capitalism to materialism and selfishness. Her coffin bore not a cross but a dollar sign!

As an immigrant from the Soviet Union, Rand brought to Americas shores a reactionary economic belief system that became another ism. But her ideology retained Kremlin-brand atheism.

Though religion does continue to play a role in Republican circles, honest observers recognize that too often it has been reduced to a tool for fake God endorsement. Buckley was not so crass, but regarded religion as necessary for promoting our Lincolnesque better angels.

Today, many politicians prefer sharp tone over civil discourse. Such leaders operate as if they do not believe they will one day be judged by God. Religion, sometimes even its veneer, has the power to elevate behavior over dishonesty as well as promote a show of respect toward political opponents.

Buckley was not perfect, but he was a thinker and a life-long learner. His adamant position on states rights cast him on the wrong side of history with respect to civil rights, but near the end of his life, he confessed that he had been wrong and that federal intervention to end Jim Crow was the right action.

Republicans would do well to return to the political wisdom of Buckley. It could make the GOP great again.
