Saturday, Sept. 12, I will be marching shoulder to shoulder with union sisters and brothers in the New York City Labor Day Parade. This year’s theme is “We Are NYC: Working Men and Women Are What Make Our City Great.”

Our contingents will proudly display that we are a mosaic of people. Nearly every nationality in the world is reflected in our city’s unions and within 1199SEIU. This great diversity strengthens our family of unions and enriches our culture, our city and our nation.

The parade also will refute the venom that has recently fouled our nation’s airwaves. Some of the presidential hopefuls are attempting to outdo each other with their xenophobia and scapegoating of immigrants. Real estate mogul Donald Trump ignited a firestorm of criticism with his hateful remarks about Mexicans. A few Republican presidential hopefuls took him to task for those remarks, though most remained silent.

Former Florida Gov. Jeb Bush, one of the candidates who criticized Trump’s slurs, does not appear to believe that people of Asian descent warrant the same respect. Last month he used the term “anchor babies” to criticize mothers who travel to the U.S. to give birth to their children.

Defending himself from charges that he had used a derogatory term frequently used to stereotype Latinos, Bush told the media that the pejorative was “frankly more related to Asian people.” Our union’s secretary-treasurer, Maria Castaneda, who heads the Asian American Pacific Islander Caucus of SEIU, expressed our sentiments when she wrote: “Jeb Bush’s attempt to walk back his offensive ‘anchor baby’ comments shows how out of touch he is with the everyday lives of Asian-Americans. The way that he tried to play the Latino community against the Asian-American Pacific Islander community shows contempt for both.”

The attack on the Latino and Asian-American Pacific Islander communities with talk of deportations and citizenship rights not only reflects contempt but also lays bare these politicians’ attempts to split our communities of color and working people as a whole.

The attack also reminds us of the unbreakable connection between the struggle for African-American equality and the rights of all. The 14th Amendment to the Constitution is enshrined in U.S. history as the cornerstone of American civil rights, ensuring due process and equal protection under the law to all persons. It further states that all persons born or naturalized in the United States and subject to its jurisdiction are, in fact, U.S. citizens. That was not always so. In the 18th century, African-Americans were left out of the U.S. Constitution. In the 19th century, the Supreme Court, in its infamous Dred Scott decision, ruled that African-Americans, whether enslaved or free, did not have the rights of citizenship.

It took the Civil War, the bloodiest conflict in our nation’s history, before African-Americans were granted citizenship. And every time African-Americans have advanced on the road to full equality, others have also extended their rights, particularly women and other people of color. For example, under the due process and equal protection clauses of the amendment, Hernandez v. Texas affirmed that people of Mexican descent and all other racial groups have the right of equal protection. Roe v. Wade affirmed the right (though limited) to abortion, and Obergefell v. Hodges legalized same-sex marriage.

At every juncture where we have made significant strides, we’ve also faced a backlash. The passage of legislation or even an amendment to the Constitution does not guarantee enforcement. It was not until the passage of the Voting Rights Act in 1965 that we began to gain political power and elect representatives whose ethnicity reflects the diversity of our nation, but even that today is under attack.

The Supreme Court’s 2013 decision in Shelby County v. Holder cut out the heart of the Voting Rights Act by invalidating the preclearance provision. States have since passed sweeping voter restrictions in an attempt to dilute the pool of voters most likely to vote Democratic.

“In 2014, the first post-Shelby election, thousands were turned away by new restrictions in states like Texas and North Carolina,” wrote Ari Berman, the author of “Give Us the Ballot,” in an Aug. 6 op-ed article in The New York Times. He warns that this outcome could be a disturbing preview for 2016.

Denying us the right to vote is just another method of negating our citizenship.

It springs from the same soil that would deny citizenship to other people of color, but if we keep our eyes on the prize of political, economic and social equality for the many and not the few, we will not be diverted by attempts to weaken our unity.

That unity will be on display at the New York City Labor Day Parade Sept. 12 in Manhattan. Join us.
