Don't we already have that?
State's rights as code:
States' rights as "code word"
Since the 1940s, the term "states' rights" has often been considered a loaded term because of its use in opposition to federally mandated racial desegregation and more recently, same-sex marriage.
During the heyday of the African-American civil rights movement, defenders of segregation used the term "states' rights" as a code word—in what is now referred to as dog-whistle politics—political messaging that appears to mean one thing to the general population but has an additional, different or more specific resonance for a targeted subgroup. In 1948 it was the official name of the "Dixiecrat" party led by white supremacist presidential candidate Strom Thurmond. Democratic governor George Wallace of Alabama, who famously declared in his inaugural address in 1963, "Segregation now! Segregation tomorrow! Segregation forever!"—later remarked that he should have said, "States' rights now! States' rights tomorrow! States' rights forever!" Wallace, however, claimed that segregation was but one issue symbolic of a larger struggle for states' rights; in that view, which some historians dispute, his replacement of segregation with states' rights would be more of a clarification than a euphemism.
In 2010, Texas governor Rick Perry's use of the expression "states' rights", to some, was reminiscent of "an earlier era when it was a rallying cry against civil rights." During an interview with The Dallas Morning News, Perry made it clear that he supports the end of segregation, including passage of the Civil Rights Act. Texas president of the NAACP Gary Bledsoe stated that he understood that Perry wasn't speaking of "states' rights" in a racial context; but others still felt offended by the term because of its past misuse.
