Fifty years ago, when President Lyndon Johnson signed the Civil Rights Act of 1964, I was in elementary school and had no clue about the law that would drastically change daily life for African-Americans. I surely had no idea how it would improve life for white Americans like me.

This historic legislation outlawed discrimination on the basis of race, color, religion or national origin at “places of public accommodation.” The movie theater I frequented had to discard its “coloreds only” entrance and the segregated balcony. Restaurants where we ate had to let African-Americans out of the kitchens and into the dining areas. My future friends, like state Sen. Reggie Tate of Memphis, were no longer excluded from admission to the Mid-South Fair six days a week.

The new law gave the U.S. attorney general authority to seek redress when school boards deprived students “of the equal protection of the laws.” Two years later, my school in Weakley County, Tennessee, was desegregated. And for the first time, I began to spend time daily with African-American children. I had new friends in the classrooms, and the lessons went beyond reading and writing.

After signing the Civil Rights Act, President Johnson said to an aide, “We (Democrats) have lost the South for a generation.” The president underestimated the political impact, which continues now two generations later.

In 1966, just two years later, the people of Tennessee for the first time popularly elected a Republican to the U.S. Senate.

In 1968, in Memphis, the sanitation workers went on strike and Dr. Martin Luther King Jr. was struck down. In Nashville the Republicans took control of the state House of Representatives for the first time since Reconstruction.  Then in 1970, Tennessee elected a second Republican to the U.S. Senate, throwing out Democratic Sen. Albert Gore Sr.

Despite the backlash, the Civil Rights Act changed customs and changed society. With those changes, what could not have been imagined in 1964 became reality in 2008: An African-American was elected president.

Yet some Republicans responded to this historic progress with crude jokes and racist appeals to fellow bigots. In just one of many examples, a Tennessee Republican state legislative aide sent e-mails caricaturing President Barack Obama’s official portrait as two cartoon eyes peering from a black background.

When in 2010 I ran for Congress, racism was too easy to find. I can still see the angry face of the man at the duck supper who responded to my handshake with “Lemme talk with you about your (N-word) president.” And the scowling man at the rodeo who snarled, “I don’t shake hands with darkies or Democrats — and they’re often the same.”

Thankfully, most Republicans are not racists. But while most Republicans would never discriminate, degrade or demean, their leaders’ legislative actions still repress voters and reverse progress.

All over the country, Republicans are pushing new impediments to discourage and decrease voting by minorities and low-income citizens. While Republicans say they oppose big and oppressive government, they rammed through Tennessee’s government ID law, now notorious as one of the nation’s most burdensome. Only certain government cards now are acceptable at the polls, after Republicans outlawed using a Social Security card or even photo ID cards from the Memphis public library or the University of Memphis. Those without a driver’s license – nationally, 25% of African-Americans – now must go to a driver’s license station, but fewer than half of our counties even have such a station.

Republicans claim these laws fight voter fraud, but instances of persons trying to vote while using someone else’s identity are almost nonexistent. And researchers at the University of Southern California showed strong evidence that “discriminatory intent underlies legislative support for (these new) voter identification laws.”

The first book of the Bible teaches, “So God created humankind in his own image, in the image of God he created them.” God’s image does not have a color, but it does have a creed. The Apostle Paul put it this way in Galatians 3: “There is neither Jew nor Greek, there is neither slave nor free, there is neither male nor female, for you are all one in Christ Jesus.”

Our American ideals long have taught that we are one. The Great Seal of the United States proclaims “E pluribus unum” — from many, one.

But it was just 50 years ago today that statesmen and idealists and people of a deep faith in Almighty God and in America together created the Civil Rights Act of 1964. Let us celebrate their good work for justice and freedom. And let us carry on their good work, so all God’s children can live in peace and love in truth.
