Yet, these same Americans also understand that we do not live in a post-racial America, as so many of us had hoped after the election of Barack Obama as the first African American president in U.S. history. Many of these same Americans see that racism, sexism and religious bigotry remain omnipresent parts of the American experience and believe that our political parties cannot pretend that these problems no longer plague us. 

This July 4, these same Americans will remember the Republican Party of American greats like Frederick Douglass, President Abraham Lincoln and Sojourner Truth and wonder how that party lost its way. The most vocal and powerful members of today’s Republican Party have made it clear that there is no longer any room in the GOP any African American, woman or person of color who dares to speak out against discrimination and demands justice for all as Douglass, Lincoln  and Truth did hundreds of years ago. 

In that 1852 Independence Day speech, Douglass asked:

What, to the American slave, is your 4th of July? I answer; a day that reveals to him, more than all other days in the year, the gross injustice and cruelty to which he is the constant victim. To him, your celebration is a sham; your boasted liberty, an unholy license; your national greatness, swelling vanity; your sound of rejoicing are empty and heartless; your denunciation of tyrants brass fronted impudence; your shout of liberty and equality, hollow mockery; your prayers and hymns, your sermons and thanks-givings, with all your religious parade and solemnity, are to him, mere bombast, fraud, deception, impiety, and hypocrisy -- a thin veil to cover up crimes which would disgrace a nation of savages. There is not a nation on the earth guilty of practices more shocking and bloody than are the people of the United States, at this very hour.

This July 4, as we celebrate all that is good about America, many will remember then-Republican presidential candidate Rick Santorum, singling out African Americans in promoting entitlement reform, insinuating that African Americans don’t want to earn a living and simply want a handout. African Americans will remember that, during a campaign event in Iowa in January before a predominantly white audience, former Pennsylvania senator Santorum said, “I don’t want to make black people’s lives better by giving them somebody else’s money. I want to give them the opportunity to go out and earn the money.”

This July 4, as we celebrate all that is good about America, many will remember those who supported Arizona’s draconian immigration law, calling it a "model" for the rest of the country, while rejecting the Dream Act that would have provided a pathway to citizenship for some young illegal immigrants.

This July 4, as we celebrate all that is good about America, many, including those who otherwise believe in “conservative principles” will be reminded of Douglass’s haunting words and will mourn the fact that the Republican Party of today is not the Republican Party of Douglass, Lincoln or Truth. In November, it is quite likely that even those Americans who embrace conservative principles will find a more welcoming home—and all of the promises of “our” Declaration of the Independence—elsewhere.
